Error 1717: the interface is unknown

After restarting a Windows 2000 Advanced Server, I got the following error:

Error 1717: the interface is unknown

I also could not open the Event Viewer.

After comparing registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog, I discovered that event log were logging into a missing directory, I created them again and then restarted Event Log Service and everything works fine.

  1. On a small business server 2008 sp2 server, we got this error when trying to start DNS, AD topology mapper, other services. Issue was that the event logs themselves in \%systemroot%\system32\winevt\logs would not open from another machine - the error was "file not found".
    Removed the log files. Started the event viewer. It started. Started some other services. They started. Rebooted the server.

    We're up. Thank you for putting this online. You directly helped.

  2. Thank you Dave , your solution for Windows 2008 worked as magic

    Thank you so much!
    Had exactly the same issue on a SBS 2008 and your solution brought the server back to work :-)
