April 28, 2007

You might have encountered issue with flushing dns at times and having difficulty to login to the client with error codes on network. You might try the following option to repair the connections.

But the most important thing before you proceed to do this, make sure you do have a LOCAL ADMINISTRATOR ACCOUNT else you would be logged out from the machine.

How to reinstall TCP/IP in Windows 2000

You might have to reinstall TCP/IP to help resolve some issues, such as improperly configured bindings, dialup clients that are unable to connect to the RAS server, NIC drivers that do not properly bind to the TCP/IP protocol, etc.

To remove TCP/IP in Windows 2000:

1. Click to clear the TCP/IP check box from all dialup and LAN connections in “Network and Dialup Connections”.
2. Install another protocol (NetBEUI or NWlink) to maintain a placeholder for each conneciton.
3. Restart your computer
4. Reinstall TCP/IP, and restart your computer again.

How to reinstall TCP/IP in Windows XP
applies both to the Home and Pro editions of XP

In Windows XP, the uninstall button is disabled for the TCP/IP protocol. The TCP/IP stack is considered a core component of the operating system, and it is not possible to uninstall it. Still, in some extreme cases, the most appropriate solution is to reset the TCP/IP stack back to a default state…

There is a NetShell (netsh) command-line scripting utility for the configuring and monitoring of Windows XP networking. Using this tool, a reset command is available that rewrites pertinent TCP/IP registry keys to achieve the same result as the removal and the reinstallation of the protocol. The following registry branches are reset using this tool:

SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\

Comand usage

Simply type the following in Command Prompt:

netsh int ip reset c:\resetlog.txt

“c:\resetlog.txt” being the logfile generated by netsh to store changes being made. If the file exists, the new log will be appended to the end of the existing file.
