I am running Arcserve 2000 on a Windows 2000 Server. I am trying to back up 4 Netware servers using the Netware Client Agent. When I initially load the Netware Agent, my backup jobs run fine with no errors. If I do not unload and reload the Netware agent, my jobs fail with a 8522 error, "failed to receive data from the client agent". The problem even occurs if the client agent is loaded for a few hours before the job is scheduled to run. I have tried every proposed solution from Computer Associates but nothing has helped. My Netware servers are version 5.1, SP3. I have applied all service packs to Windows 2000 and Arcserve. Has anyone else had this problem?
