You Don't Have Administrative Rights To Run The Command & Make Sure You Are in Administrative Account

At least once in your life you might have encountered the error message You don't have administrative rights to run the command and make sure you are in Administrative account while running certain DOS commands on DOS window. The funny part is, you are already logged in to administrative account. Though you are logged in to admin account, DOS is not able to run certain commands due to lack of admin privileges. One of the major reasons to get this error message even though you are in administrative account is User Account Control issues. In this article we can check the reasons and solution for the error message.
You Don't Have Administrative Rights To Run The Command & Make Sure You Are in Administrative Account


Reason For Error You Don't Have Administrative Rights To Run The Command

To run certain codes on DOS, User Account Control requires us to start the command prompt as an administrator. So the solution for the error message you don't have administrative rights to run the code and make sure you are in Admin account is to execute DOS on your computer as admin.

Steps to Run Command Prompt as Administrator

  1. Click on Windows Start and click search

  2. On search type cmd

  3. Right click on the command prompt icon and select Run as administrator.
    admin privilege

On the new DOS window you will not receive same error message while trying to execute a code which needs admin privilege. So now onwards if you receive any privilege related issues while executing any commands on Command Prompt you can overcome that by simply running the command prompt as administrator.

Unlock Secret Windows Administrator Account Using Windows Hack

Not so many users are aware of the default administrator account present on their computers. This default admin account is created while installing Windows on their computer. In most cases it is not password protected especially in  Vista and XP. So it is important to assign a password to ensure the safety of your computer. This tutorial explains how to unlock the hidden default admin account available on a Windows computer. If you do not set any password for it while installing Windows 8 and 7, it will be unprotected without password. However, this tutorial just focus on introducing the concept of secret Windows user login on every computers and the Command Prompt trick to enable or disable it.

How to Find Secret Profiles

Before explaining how to activate secret profiles on a laptop, let us learn how to get the list of all Microsoft profiles. We can print the entire Microsoft OS profiles on DOS window using net user. To run this code, you have to start DOS window as administrator. Type it and press enter to get the list of all Microsoft OS profiles created on the laptop.

How to Unlock Default Administrative Account On Windows PC

To turn on the default Administrative Account in Windows 7 and Vista computers, follow the steps provided below.
  1. Start Command Prompt in Admin mode

    Right click on Command Prompt from Start menu and click on Run as Administrator. To learn more about it, visit the link below.
    Open DOS Prompt in Run as Admin Mode

  2. Type Net user administrator /active:yes on Command Prompt and press enter.
    Start hidden Microsoft profile
Now onwards you will be able to see default Windows User profile on  welcome screen.

Disable Default Windows Administrator Account

If you do not want to list the default administrative account on welcome screen, you can disable it by a simple Command Prompt command.
  1. Start DOS Prompt in Run as Administrator mode

  2. Type Net user administrator /active:no and press enter
Disable default Windows administrator account

Here in this picture, I have disabled the default Administrator account using the command net user. If you have any doubts about the profiles created on your computer, by simply typing net user on command prompt, you can find them. The same trick will reveal all hidden users on a laptop. On command prompt, all user profiles will be shown after running the net user command. If there any disabled admin account, you can simply enable it by using the command Net user [user profile name] /active: and you can reclaim your access.

To enable or disable the default Windows admin profile, you must be in administrator account. If you forgot the password to login, follow the instructions provided in the link below.

List Of Free Proxy Software and Web Proxy Servers To Browse Anonymously

Proxy server is a middle man acting between your computer and the web server. For example if you are accessing Google from your computer using a proxy named X, your computer is not receiving information directly from Google but X is receiving services and send it back to your computer. So naturally the web server does not know your computer and it thinks it served X. So by using a proxy server, theoretically you can browse anonymously and also help you to bypass firewall restrictions too. This guide gives a short introduction of Proxy Servers with a number of popular server addresses. There are two types of Proxy services.
  1. client based (Software Installed on your PC)

  2. Web based proxy servers (No is software installed on your PC)
If you are expecting high anonymity, you must go for premium servers but for normal users web based proxy server is enough. Here I give a list of free popular servers.

1. Client Based


Please note that some proxy software products might contain malware and user should use it at their on risk. CoreNetworkZ is not providing any guaranty for the proxy software provided below.

  1. CCProxy

    You can download and install on your computer to start browse anonymously. In addition to the anonymous surfing, CCProxy offers features like DSL sharing, cable modem sharing, wireless sharing, satellite sharing, parent proxy server connection sharing etc. To download and install CCProxy, click on the link provided below.

Working

Proxy servers are iterating between your computer and rest of the Internet. The request from your computer goes to the proxy server and it resubmits the request to the actual destination. So they will get the IP address of the proxy server instead of your computer's IP address and your privacy will not be compromised. The same principle is used for bypassing the firewall. The firewall detects the address of proxy server instead of the blocked website. So the packets will go through the firewall.

Your computer------------->Proxy Server------->Website


Major Uses

There are two kind of uses from a real proxy server.
  1. Hiding your Identity in the Internet

  2. Bypassing restrictions


Advanced Services


Proxy servers has many uses other than just an anonymous surfing and bypassing the firewall restrictions. In a large enterprises proxy server is associated with a gateway server that separates the enterprise network from the outside network and protects the enterprise network from outside intrusion. That means a good proxy server can act as a firewall. It can also act as a cache and so virtually the Internet speed can be increased.


Types Of Proxy Servers

They are classified according to the way, they operates.
  1. Caching

  2. Web based

  3. Content-filtering

  4. Hostile

  5. Intercepting

  6. Transparent and non-transparent



Testing a Proxy

It is better you check your IP address when you are using proxy server to detect how much anonymous you are. So of the IP address checking tools I use are:
  1. http://www.ipaddresslocation.org/

  2. http://www.ip-adress.com/

How to Add a Wireless Router to Cable Modem and Share Restricted Broadband

Cable broadband is as popular as DSL broadband but the steps to add a WiFi router to both connections are different. This article explains the steps to add a wireless router to a cable modem to extend the network. Modern cable modems have WiFi feature but if you are using standard one without WiFi feature, you can use this guide to add WiFi to your current home or office network. Here I use a cable modem, Linksys WiFi router, one desktop PC and a laptop to demonstrate the configuration.

Current Network Diagram

Without telling the current network diagram, I cannot explain the procedure. I have a cable modem connected to my desktop PC. MAC address of the Desktop is registered with my cable broadband company and I do not think they want to share the Internet connection with other devices in my home. Now I want to share this restricted Internet connection to my laptop without registering the MAC address of the laptop.  I have bought a Linksys router for this purpose and want to extend the Internet to my Wireless Laptop through it.

The procedure to add Linksys Wireless Router to a cable modem

  1. Make sure that you are able to go online through modem.

  2. Connect the output line of modem to the WAN port of your router.

  3. Connect the first computer to the LAN port of the  router.

  4. Power on the Router and wait until the Wlan and Ethernet light are on.

  5. Open browser window and type http://192.168.1.1 but please note that the login IP will be different for different vendors.

  6. It will ask you for username and password. Enter the default values provided by the vendor.
    add tablet to wifi with Comcast combination modem/router

  7. Setup page looks like below.
    Configure


    The configuration

    • Automatic configuration - DHCP should be selected
    • The IP address should be 192.168.1.1
    • DHCP server should be enabled

  8. MAC address clone

    Under Setup you can see MAC address clone. Click on that.
    MAC

  9. Click on clone MAC address and save settings.
    MAC clone

  10. Set a router password

    We need to change the default password to a good one. After typing the new password, click on save settings.
    Change password

  11. Configure Wireless

    Click on Wireless tab and you can give any name as SSID. You may choose wireless channel 6. Other two possible channels are 1 and 11.

  12. Now under wireless security, you can enable encryption.
    encryption on cable modem

    After saving the settings reboot the device.

You have successfully configured your router with a cable modem. Right now the broadband connection from the cable ISP is shared between my laptop and desktop computer. I have bypassed the restriction to use Internet on single computer by cloning the MAC address of my registered computer to to router and use it to divide the connection. MAC address registering is an old trick played by cable broadband service providers to limit the number of devices accessing their broadband connection. I have written an article about it a few weeks ago. You can read that article by visiting the link below.

Error 1747 : The Authentication Service is Unknown in Vista

Yesterday I encountered a strange error with Windows Vista laptop while troubleshooting WiFi connectivity problems. We were at a public hotspot but his laptop failed to join the network. It displayed a message Windows cannot find wireless networks. While opening Dell Wireless utility, it shows the status of Dell adapter as disabled. However, in Device manager, it shows the device is working properly. Possible issue might be with Wireless Zero Configuration service. For Vista and later versions, WLAN AutoConfig is doing the same function. We accessed services page and found the the specific service in stopped state. We pressed the button start but it failed with a strange error. It is given below.

Service cannot be started Error 1747 : The Authentication Service is Unknown


Though it was the first time I encountered such an error, we fixed it quickly. This tutorial explain how to deal with the error Service cannot be started Error 1747 : The Authentication Service is Unknown and solve it quickly.


Troubleshooting steps
  1. Make sure Wireless button on the laptop is ON

  2. Check Firewall settings

    Faulty settings on the Firewall installed on your computer may prevent it from accessing Internet. So for troubleshooting purpose we need to disable it.

  3. Services must be running with full permissions

    It is important to make sure the services are running on the PC with full permissions. To verify it, follow the registry path and make sure your current user has full permissions.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services


  4. Try Windows Socket reset

    To do tit, type the following command on DOS prompt and press enter.

    netsh winsock reset

    To go with advanced Windows Socket permissions follow the registry.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinSock2

    Right click on the registry entry and click on permissions. Make sure that Winsock and Winsock2 has full permissions. Before testing with Registry, I recommend you to read the article provided below by visiting the link.

How to Test Local Network For Connectivity Issues

It is very frustrated when you are unable to access Internet on your computer but the ISP technical support repeats everything is fine at their side. There are so many reasons which can prevent connectivity on your local network like DNS issues, faulty Ethernet cable or modem etc. This article explains basic troubleshooting steps you can follow to test your local network when you face Internet connectivity or file sharing issues. To test a local network, we do not need high networking knowledge. If you read this tutorial carefully, you will find it very simple.
  1. Find Network Topology

    At first you must understand how devices are connected to the LAN before starting the troubleshooting. In this example I assume the PC is connected to the router using an Ethernet cable. Router is connected to the modem. So the network topology is as below.

    Modem----Router---PC

  2. Ping Router

    We need to ping the first device connected to your PC. Here in this example, it is router. So you must type the following command on Command Prompt and press enter.

    ping [router IP]

    If you do not know the router IP address, type the following command on Command Prompt and press enter.

    ipconfig

    Now you will get the Default Gateway address. It is the router IP address(I assume it is 192.168.1.1). So to check the connection between router and you computer execute the following commands.

    ping 192.168.1.1

    We need to ping the router even if you are getting default gateway because this value may be shown on DOS from cache. If you are getting reply then we can proceed to step2.

  3. Ping the Modem IP

    If you do not know the modem IP address, I suggest you to follow the instructions provided in the link below.
    How to Find Log on IP Of a Device

    Here I assume the respective IP address is 192.168.0.1 and to ping modem, use the following command.

    ping 192.168.0.1

    If you are getting replies from destination, connection between your computer and modem is perfect. The issue must be at ISP side.

  4. No Reply From Modem

    What if you are not getting valid replies from modem. In this case you must change the way of troubleshooting. While your computer is receiving replies from the router and not from modem, we can pin point the issue as follows.

    • Your modem has no connection to the router.

    • Modem is faulty

    To fix the issue follow the steps below.

    • Check the Connection

      Check the connection between modem and router. Make sure the LAN lights for respective ports are on. If you are not sure, unplug the cable and reconnect it.

    • Power cycle

      We need to power cycle the entire network or at least modem. Disconnect power from the device and wait for one minute to reconnect power. To learn more about this step, I suggest you to read the instructions provided in the link below.
      What is Power Cycle and How to Do It

Cannot Ping 127.0.0.1 and No Reply From Local Host

When we send ping packets to local host or loopback address (127.0.0.1 to 127.255.255.254), they will be rerouted to the PC. Even if your Ethernet adapter is not connected to any modem or router, you will get valid reply when you ping loopback IP. However, in some cases you may not get replies from 127.0.0.1 and this article explains the reasons for it.

There are two reasons which prevents your computer from getting replies from 127.0.0.1. They are provide dbelow.
  1. TCP/IP suit installed on your laptop is corrupted

  2. Ethernet adapter is not working

Fix

Now let us troubleshoot each cases.

  1. Reset TCP/IP

    To fix issue with TCP/IP suit on your computer, use the following commands. You can type them on Command Prompt one by one and then check for the issue.

    • ipconfig /flushdns

    • netsh int ip reset c:\tcp.txt

    • netsh winsock reset

    After resetting the windows socket and TCP/IP suit, we need to restart the PC. After restarting the computer we need to check whether the issue persist or not. If still we cannot ping the loop back address the only possible chance is corrupted Ethernet Adapter.

  2. Test Adapter

    Since the TCP/IP suit is installed properly, only reason that may prevent local host from communicating properly is the faulty Ethernet adapter. We can test the status of an adapter in device manager. To learn it properly, I recommend you to follow the instructions provided in the link below.

Getting Reply From Loopback Address But Can't Ping Other IP Address

Loopback address also called local host is a reserved IP address. If we send packets to this IP address it will be rerouted to the computer itself. So loopback address is used to troubleshoot TCP/IP related issues on a PC. This article explains a rare situation where you cannot ping any IP address including the DNS server but can successfully ping loopback address. Before explaining this issue, I would like to explain the concept of loopback. IP address in the range 127.0.0.1 - 127.255.255.255 are private and can be used as loopback but we normally use 127.0.0.1 as the loopback or local host. Now let us check the scenario where you can successfully ping 127.0.0.1 but not any other external IP.


Explanation

Here I ping 4.2.2.2 from command prompt but it failed to get valid reply from it. However, when I ping 127.0.0.1, I am getting valid replies. Possible reasons from no valid reply from DSS server though I get replies from loopback address are:
  1. The TCP suit on your computer might be corrupted

  2. Connection Issues in the network

  3. There is no internet connection from your service provider.

If you are getting reply from the loop back address it shows the TCP/IP suit is working on your computer. However, it is important to verify it by sending ping packets to 127.0.0.1 and analyse the reply.
  1. Click on start

  2. Click on run and type cmd on it then click OK(On Vista type command on search and press enter)

  3. Ping Loopback

    On the command prompt type the following command ping 127.0.0.1 and press enter key. If you are getting replies, then the TCP/IP suit is fine. If not, you must reset the TCP/IP suit on your computer. To learn how to do it, I recommend you to visit the link below.
    There is No Reply From Loopback

After verifying the status of TCP/IP suit, we must check the network connection. Here we must make sure there is no loose connection or faulty cable. Verify the Ethernet cable connected properly between your LAN port and Modem/router. Also verify the quality of Ethernet cable.

Can Ping Global DNS Server IP Address But Unable To Open URL

Domain Name System (DNS) converts website address we type on the address bar of a browser in to corresponding IP address to enable Internet access. It is very important to establish a connection between your computer and a web server. It is one of the common issues to block access to Internet on a PC. We can identify this issue by pinging website IP address. Users can successfully ping public DNS addresses like global or open DNS but they cannot open webpage with URLs, if they are facing domain to IP conversion issues. It is like you can successfully open a website by typing the IP address of that website but you cannot open the website by using the domain name. This tutorial explains how to deal with this situation where you can ping website IP address successfully but unable to open it on browser by typing its URL.

Can Open Website by IP address But Cannot Access With Domain Name

If you want an example of this issue, see the example below.
  1. When I try to access Internet through browser, I failed to go online

  2. When I ping global DNS server, I get replies

Troubleshoot Wrong DNS Settings Issues
  1. Go to command prompt try the following commands

    ping www.corenetworkz.com

  2. If you are not getting reply from www.corenetworkz.com, try to ping public servers like global DNS server or Google DNS server.

    ping 4.2.2.2

    Now we have two chances either you got valid replies or no valid replies.

  3. Solve the DNS Issue

    If you are getting valid replies when you ping global DNS server, the issue can be concluded as follows. You are able to communicate with Internet server but cannot communicate with a website(eg: www.corenetworkz.com). Reason is the wrong settings on your computer. To fix the issue we need to assign correct settings on your computer by following the steps provided in the link below.

Example

Here I am going to explain it by an example. Here I am going to ping Google by both its domain name and IP address.

Domain Name: www.google.com
IP address: 74.125.236.165

  1. Ping Google.com

    My computer doesn't resolve URL to IP address conversion properly and thus it failed to find the host google.com. You can verify it by analyzing the image given below.
    cannot open google

    If you cannot open Google.com on your browser, you will get this reply while ping the URL from command prompt. However, if you ping the IP address of Google, your computer will get valid replies. It clearly tells the issue is with converting the host name to respective IP address.

  2. Assign Valid Domain Name Server Address

    After changing the Domain Name System details on PC, there won't be any issues with opening Google on browser by typing www.google.com.
