2.5 89xx Errors

8901 Cannot use TCP/IP services

Source: GroupWise engine; TCP/IP communication.
Explanation: A fundamental TCP/IP call failed.
Possible Cause: TCP/IP services couldn’t be used. It is possible that TCP/IP is loaded incorrectly on this server.
Possible Cause: Cannot load WINSOCK (Windows only), or the WINSOCK that did load is not supported. DNS is not loaded and you are trying to resolve DNS names.
Action: Correctly configure TCP/IP on the server.

8902 Cannot load TCP/IP services

Source: GroupWise engine; TCP/IP communication.
Explanation: TCP/IP load failed because a required file was missing.
Possible Cause: Unable to load TCP/IP services because one or more of the required files is missing: winsock.dll, wsoc32.dll, or tcpip.nlm.
