Question : Brightstor 12.5 Exchange Agent issue

I have upgraded a stand alone server from Arcserve 11.5 for windows to 12.5. When trying to browse the existing backup job I am unable to expand the "dbaxchg2" tree as I receive the following error message:

Backup Agent Error - - (318) "Can not get the information from Registry"
When i click "ok" at this error message I am presented with a security login box but it will not accept any domain user name and password or the caroot account details.

If I try to create a new backup job there is no "bdaxchg2" at all.
I have therefore been unable to backup users individual mailboxes.

Answer : Brightstor 12.5 Exchange Agent issue

A remote session with CA seemed to sort out the login problem although because i wasn't present at the time I don't know how it was resolved.
Anyway, once we could see the mailboxes we ran a backup and the served locked up and had to be power cycled. After another few days on the phone to CA I noticed the server was crashing when it started the Microsoft Exchange Writer so I deselected this from the backup job and it now works fine.
