TCP/IP communications failure between the client and the server machine.
An attempt to connect to the server using TCP/IP communications failed. This can be a result of incorrect TCP/IP option settings in your client options file. This error can also occur if the LAN connection went down or if your system administrator canceled a backup operation.
The TSM client ends.
Retry the operation and make sure the LAN is up. Make sure that both the TSM server and the TSM client are up and running.
