What version of SQL Server?
What service pack level?
Can you browse the SQL server in the Backup Manager?

What version of SQL Server : 7.0
service pack level : sp3

No I cannot the SQL server in the backup manager because of this :
Backup Agent error (85) 'Invalid user ID or password was sbmitted'

I would make sure that you have your ARCserve patches up to date. Have at least sp2a installed and maybe take a look at the list of patches for 6.61 SQL agent:

Something else to take a look at would be the authentication method you are using. If you are using mixed, try using both 'sa' and Administrator. If you are using Windows Authentication, try browsing while logged in as Administrator and change the Job Engine (if SQL is local) or Backup RPC Server (if SQL is on another machine) to start using Administrator. There may be a problem of ARCserve not impersonating you properly and cannot be authenticated by SQL.

Good luck
