Many times a corrupted registry entry (usually caused by a virus, spyware, or malware) can cause TCP related errors. For example, your network connections are suddenly and mysteriously gone or you get various TCP Transport errors. To fix this problem, try the following:
- Uninstall all Network Connections in the Network Control Panel and reboot.
- From another machine download WinSock Fix XP
- Run winsockfix.exe which fixes your registry entries and clears any errors.
- Restart the system and install the network connections.
- Run every anti-virus and anti-spyware program you can find.
This happened to my PC several months ago. I had visited a website and all of a sudden my AVG Anti-Virus warned me of an infected webpage. My computer froze and when I rebooted I had no network or internet connectivity. It took me several hours to fix it! Had I known about this tip beforehand I would have saved myself hours of work.
