Hello, We are getting the following in our logs. and CPU usage seems to be higher than normal.

DCOM was unable to communicate with the computer CLSTGSRVEVAULT11 using any of the configured protocols; requested by PID 3fc8 (C:\Program Files (x86)\Enterprise Vault\ArchiveTask.EXE).

Does anyone have any idea what might be causing this? We have no idea what CLSTGSRVEVAULT11. None of our machines have that name. 

Thanks,
