256986 Description of the Microsoft Windows Registry

SYMPTOMS: When you try to connect your computer to a network, you may receive the following error message:
An operation was attempted on something that is not a socket. This symptom occurs on a computer that obtains an IP address from a Dynamic Host Configuration Protocol (DHCP) server. If you assign a static IP address to your computer, you do not receive this message.

CAUSE: This issue may occur if you have a third-party product installed that uses Windows sockets and also uses the ipconfig, release, and renew commands. The Windows sockets registry subkeys may be corrupted.

RESOLUTION: Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. To resolve this problem, use either of the following methods.

Method 1 We recommend that you use Method 1 if either of the following conditions are true:
You only have one computer.
You do not have access to a computer that is similar to the first computer where you experienced the symptoms that are described in the "Symptoms" section. A computer that is similar to the first computer is another computer that has the same operating system version and a similar hardware configuration.Use Registry Editor to export and delete the Winsock and Winsock2 registry subkeys, and then remove and reinstall TCP/IP on Microsoft Windows 2000 or Microsoft Windows XP. To do this, follow these steps.
