While initializing TCP/IP communications for administrative sessions, the server has failed to connect to a master socket on which to listen for clients. The reason code is the return code from the TCP/IP bind API.
Server operation continues, but the server cannot accept administrative sessions from clients using the TCP/IP protocol. This also includes server to server sessions, storage agent to server sessions, and library client to server sessions.
Ensure that no other application is using the port number specified in the server options file with the TCPADMINPORT option. If the server is brought down and then started immediately, you can be within the TCP/IP one minute timeout period for port reusage. Bring down the server, wait one minute, and then restart the server. If that does not work, it may be necessary to restart Windows.
