  • Hi philrober,

    Before we move on, I would like to confirm the following information with you:

    ·         Can you check the Even log of this problematic computer? and post any related error log here.

    ·         Have you install any program on your computer recently?

    ·         Can you make sure that the wsock32.dll is still existed under path “ % SystemRoot %/system32 “

    ·         What OS version of this problematic computer?

     

    Error 10091 indicate that Network subsystem is unavailable. This error is returned by WSAStartup if the Windows Sockets implementation cannot function at because the underlying system it uses to provide network services is currently unavailable. Users should check: That the appropriate Windows Sockets DLL file is in the current path. That they are not trying to use more than one Windows Sockets implementation simultaneously. If there is more than one Winsock DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. The Windows Sockets implementation documentation to be sure all necessary components are currently installed and configured correctly.

     

    Here are some work around for you reference

    1.       reset the win socket to default static, execute “ netsh winsock reset ” in command prompt.

    2.       Replace the Wsock32.dll with correct versions.

    Restart system in safe mode ,execute “SFC /scannow”, The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

    3.       Reset registry vale HKLM\System\CCS\Services\Winsock2.

    Please export this keys from a working server's, copy the export file, deleting the old version on problematic computer, importing the new version, and restarting the server.

    4.       If you have antivirus software ,I ‘d like you Scan your system with newest virus-defines.

     

    If you have any questions or concerns, please do not hesitate to let me know

     

    Thanks.
