Hi,
We get the message
Error # The RPC server is unavailable when we try to add a performance monitor on 1 server.
It was working before since we have other performance monitors.
When we test the credentials it gives the same error.
The DCOM and RPC are working on the server, I was able to connect with wbemtest and do some queries.
It is not the firts time it has done this on 2 separate installations of OpManager and the only way we found to correct this is to delete the device and add it again.
Tried those solutions with no results :
