Server 1: Using W2K SP3, main backupserver, Server 2: W2K SP3 with
Exchange2000SP3, BrightStor ArcServe9 with BOAF and ExchangeAgent

The problem is that after a succesfull backup of Exchange Bricklevel
the next backup the Bricklevel backup crashes.See next lines;

Connect Exchange Backup Agent
ERROR: Fail to open IStore: MAPI return [80004005]
ERROR: ExchEnumIStoreInitial() return [2129]
FAILED: Enumerate Information Store --- ErrorCode:[2129]

If I restart the services on server 2 (so the Exhangeserver) the
backup goes again Ok for 1 time but the next time I get the same
errors? I restart the following services;
- BrightStor Discovery Service
- CA BrightStor Backup Agent RPC Server,
- CA BrightStor Universal Agent

I don't have any idea whta this can be, the backups where running very
well for about 9 months, nothing changed.

If you have any idea please help me.
