How to Uninstall and Reinstall TCP/IP Protocol

On CoreNetworkZ, we have discussed many connectivity issues. One of the many common solutions found in different tutorials is the reinstallation of the TCP/IP suite. So, we decide to write a supporting article to cover this area. Uninstalling TCP/IP on your computer is another supporting article for our major network troubleshooting guides. Before going to the steps to uninstall TCP/IP protocol, we should understand what is TCP/IP.

TCP/IP is a protocol suite, a combination of a set of protocols which are necessary for establishing communication between computers in a network. Major protocols in TCP/IP suite are:

1. TCP
2. UDP
3. IP
4.ICMP
5. DHCP

Steps to uninstall TCP/IP Protocol

Open Network and Dial-up Connections or Network and Sharing Center
Open Local Area Connection and Click on Properties

How to Delete My Yahoo Messenger Account

I believe you heard the news about the closing of Yahoo Messenger public chat rooms. Some of the loyal users of Yahoo messenger service(YM) are angry on it, and one user asked me to share steps to delete YM accounts. Whatever the reasons Yahoo provides an option to delete your Messenger account. However, the important point to remember is you cannot delete YM account alone. The only option is to delete entire features associated.

So I recommend using the different alias if you are no longer interested in disclosing your real ID. If you are determined to delete entire Yahoo account, you can follow the steps provided below.

Go to the Yahoo Account Termination page by click on the link below

https://edit.yahoo.com/config/delete_user
Login using your username and password
Now you need to verify the termination process by filling your password
Now they will permanently disable your access to this account and put this account in the deletion queue. After 90 days, they will remove your account.

Points to Remember

If you are using any premium service, you have to cancel them before you start the deletion process.
Even if you delete the Yahoo account, it will be still in their server for 90 days

This 90 days delay in complete removal is to prevent users from doing fraudulent activities using their service. For example, if one particular user uses his messenger account to do any malicious or fraudulent activity may close his YM profile after the completion of his task.

Once his profile no longer exists in the server, he can assure safety from getting caught for his works. However, this 90 days delay is enough for legal authorities to track his user ID and the IP address used to create and manage that ID.

The above steps are enough to remove your YM profile. If you are looking for services which show whether your current contacts are invisible or offline, click on the link below.

The steps and tools provided in that tutorial will help you understand the current real status of your contacts.
Check Whether Your Contact is Invisible or Offline

Have you ever think about finding out whether the location mentioned by your YM contact is correct? Theoretically, it is possible to find out the actual location of your contact. To learn how to do it click on the link below.

Unresponsive Script- A Script On This Page May be Busy,It May Have Stopped Responding

For the past few days, I have been getting an error message on Firefox while browsing. The error message is A script on this page may be busy, or it may have stopped responding.

Type about:config on the Address bar and press enter
Click on I'll be careful, I promise!
Double click on dom.max_script_run_time

The Requested Operation Requires Elevation (Run as Administrator)

If you are trying to access certain files or services those need the elevated permission as a local administrator, you will receive an error message The requested operation requires elevation(Run as administrator). It is due to the continued efforts of Windows to protect the safety of user computer from unauthorized access to important services and applications by adding an extra layer of security which enforces users to run the application with administrative privileges only.

This Windows feature is called User Access Control(UAC) which ensure the user is accessing the program/service with necessary administrative rights.

The error message you may receive if you are trying to access the application without sufficient administrative rights looks like one below.

Error 769: The Specified Destination is not Reachable

Today morning while connecting my PC to the Internet using BSNL modem I received a message 'Error 769: The Specified destination is not reachable' and failed to access the Internet. It seems like my computer was trying to connect through WAN Miniport using PPPoE but failed to do so. So we can confirm this issue is related to PPPoE connection. This message shows additional buttons Redial, Cancel and More info and we can click on any one of them.

I clicked on redial but received the same failure message.

Possible Reasons for Getting Error 769

The major reason for "Error 769: The specified destination is not reachable" is wrongly configured the network connection.

If the network connection is PPPoE for DHCP connection (means DHCP server is enabled on Modem), your computer will not be able to find the PPPoE server and you will get this message. Another possible reason is the disabled network card on your PC.

How to Fix Error 769

To fix Error 769: The specified destination is not reachable you should follow the steps below.

Make sure Network Card is enabled:

To enable Network Card in your computer follow the steps provided in the link below.
How to Turn On Network Card on Your Laptop
Remove Extra PPPoE

Remove any PPPoE connection setup in Network Connection (If you have enabled the DHCP on Modem). There is no need to configure dual PPPoE to go online. If the modem is in PPPoE, you should delete all connections you have created on your PC using the username and password provided from ISP.
Make sure the Modem is working Properly:

It is advised to do a power cycle as an additional step to troubleshoot Error 769. To do proper power cycle follow the steps provided in the link below.

If you receive error 769 even after completing the steps mentioned above, you are advised to uninstall and reinstall adapter driver on your computer.

After uninstalling the currently installed software, you must use the latest version downloaded from the vendor website. To do this follow the steps mentioned in the link below.
Uninstall and Update Driver Installed

As we explained before, the two major reasons to get Error 769 are faulty network configuration and disabled NIC.

When you see the error message Error 769: The Specified Destination is not Reachable, you should start with the status of the Network Interface Card on your computer.

If the NIC is working fine, you should start checking the network configuration. If the issue persists, you should do a power cycle.
