Arcserve 2000 Database engine will not start 1

[jimwaring]

I've recently had a problem on a Windows 2000 server "ServerA" running Arcserve 2000 where the backup failed with error
E3530: Failed to logon to database.
W3831: Unable to find any media.
The media is recognisable via Device Manager.
The database engine is stopped and will not start, error:
E5111: Timeout waiting for the database engine to start.

I also had another server "ServerB" which also ran Arcserve 2000 and was working successfully.

Logged onto "ServerB" and cleaned the database (found this on Tek-tips a while ago):

1.) Close all ARCserve programs (i.e. Manager, Server Admin)
2.) Stop ARCserve Database Engine Service
3.) Delete all files *.CH? from the \ARCserve\database\ directory
4.) Start ARCserve Database Engine Service
5.) Start ARCserve Server Admin
6.) Select Database Engine tab
7.) Pull down the menu "Operation"
8.) Select "Initialize Database ..."
9.) Switch from "All Databases" to "The Database to be initialized"
10.) Select ONLY the Datbase "ASTPSDAT"
11.) Press the Initialize button

NOTE! This procedure will almost empty your Database.
Since the database is empty you can not restore without Merging back sessions
to your database.

Moved the ‘Database’ folder on "Server1" from
c:\program files\computerassociates\arcserve to the root of C:\ (as a backup)

From "Server1", mapped a drive to \\"Server2"\c$ and copied across the
\Program files\ComputerAssociates\Arcserve\Database folder.

Started the Database Engine.

Ran a test backup, and the scheduled backups ran OK.

I hope someone finds this useful......
