Backup Exec 2012 - Server disappeared from list, cannot chose it
We have a brand new BE 2012 installation. We installed 18 windows agents on Windows 2008 R2 SP1 French version. For some unknow reasons we have 2 of them that keep disappears from the backup Exec 2012 Server list and we can't find a way to bring them back. If we hit a refresh button, BE will remove them from the server list. We've able to create a backup job for those 2 before they went away.
Hyper-V Svr #1 - 6 Virtual machines on it with agents - works fine
Hyper-V Svr #2 (not fine) - 6 Virtual machines on it with agents - works fine except for 1 VM
We try uninstalling and reinstalling Agents but it doesn't help. We have restarted Hyper-V #2 and VM.
Any help would be appreciate.
