Move Archive failed
DCOM errors that you see usually arent bugs, the times you see them is when the services aren't started.
So the way that it works is when you install Enterprise Vault, it registers a bunch of DCOM packages which allow the EV Servers to talk to each other securely over the network,
The DCOM errors that you will typically see is that EVServer1 connects to EVServer2, through something such as Storage Archive, Windows gets the request and then launches StorageArchive.exe and all is great.
But if Enterprise Vault services are stopped, EVServer1 tries to connect and Windows tries to launch the DCOM Package and it fails because the services are stopped, which then throws an error in the system logs (i.e that this item failed to launch etc), that is perfectly normal and other applications that use DCOM would see the same issues as well
