how to resolve windows socket errors

cannot browse internet or local network? displaying errors looks like one of below

  • " unable to initialize windows socket interface error code 0, IPMONTR.DLL failed to start with error code 10107 "
  • " An error occurred while renewing interface 'Internet': An operation was attempted on something that is not a socket "
  • " An error occurred while renewing interface Local Area Connection: the requested service provider could not be loaded or initialized "
  • " The page cannot be displayed "
  • " An error occurred while renewing interface local area connection: an operation was attempted on something that is not a socket. Unable to contact driver Error code 2 "
  • " The operation failed since no adapter is in the state permissible for this operation "
  • " The attempted operation is not supported for the type of object referenced "


the meaning of these errors are the Winsock registry keys are damaged or corrupted.

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:
    • 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.

manual steps to recover from winsock2 corruption

step 1

to repair winsock in windows xp
  • go to the command prompt
  • type netsh winsock reset at the command prompt, and then press ENTER.

  • Enabling Simple File Sharing prevents the ability to assign user-level passwords to shares. When Simple File Sharing is enabled on a computer, remote users will not be prompted for a password when accessing that computer's shares.
  • If the Windows XP Professional computer is part of a Windows domain rather than a Windows workgroup, this process for enabling or disabling Simple File Sharing has no effect. Simple File Sharing always remains disabled for computers joined to domains.
