Restoring MSDB - e0008492 - Database Query Failure

Hi,

Server: 2K Advanced

Symantec Backup Exec 10d

SQL 2k Add-in used

Our server had multiple hard drive failures on the day we wanted to retire it. I have managed the following restores,

1. Master database

2. User databases

However I am failing to restore the MSDB - it reaches 99% before the above error is displayed.

Byte count never increases past 0.

Steps I am following:

1. Putting the MSDB database into single user mode.

2.Taking existing database offline

3. Replace databases or filegroups

I desperately need to recover my DTS packages, please help!
