how to determine the winsock2 key is corrupted for windows xp, use one of the following methods.

method 1 - Netdiag tool

To use the Netdiag tool, you must install the Microsoft Windows XP Support Tools. To do so, follow these steps

• Insert your Windows XP Setup CD, and then locate the Support\Tools folder.

• Double-click the Setup.exe file.

• Follow the steps on the screen until you reach the Select An Installation Type screen.

• On the Select An Installation Type screen, click Complete, and then click Next.

When the installation is complete, follow these steps

• Click Start, click Run, type Command, and then click OK

• Type netdiag /test:winsock, and then press ENTER.

The Netdiag tool will return the test results for several network components, including the Winsock. For more details about the test, use /v at the end of the netdiag command: netdiag /test:winsock /v

method 2 - use the Msinfo32 program

note - Use this method only if you do not have a Windows XP Setup CD and you do not have Support Tools installed.

• Click Start, click Run, type Msinfo32, and then click OK.

• Expand Components, expand Network, and then click Protocol.

• You will have ten sections under Protocol. The section headings will include the following names if the Winsock2 key is undamaged:

1. • MSAFD Tcpip [TCP/IP]
   • MSAFD Tcpip [UDP/IP]
   • RSVP UDP Service Provider
   • RSVP TCP Service Provider
   • MSAFD NetBIOS [\Device\NetBT_Tcpip...
   • MSAFD NetBIOS [\Device\NetBT_Tcpip...
   • MSAFD NetBIOS [\Device\NetBT_Tcpip...
   • MSAFD NetBIOS [\Device\NetBT_Tcpip...
   • MSAFD NetBIOS [\Device\NetBT_Tcpip...
   • MSAFD NetBIOS [\Device\NetBT_Tcpip...
   
   If the names are anything different from those in this list, the Winsock2 key is corrupted, or you have a third-party add-on, such as proxy software, installed.

If you have a third-party add-on installed, the name of the add-on will replace the letters "MSAFD" in the list.

If there are more than ten sections in the list, you have third-party additions installed.

If there are fewer than ten sections, there is information missing.
