Good day all,
Ok, first, thanks to all for all the assistance and tips. Next, lets clear up a couple of points:
1: The update that was installed was a security update for IE8. I cannot see that it would have ANY effect on BEWS.
2: this is for teiva-boy, it is not possible to do a rollback as this is a critical server and downtime is to be kept to a minimum.
3: As an aside, it just seems that Backup Exec is a very unstable program as I have had multiple issues since I have installed it,both on our server AND on clients servers. In fact, the ONLY client who has not had ONE day's problem, is the one who is NOT using Exchange 2003, which makes me think that BEWS is STILL not that compatible with Exchange which is sad considering that the Veritas version was brilliant. It makes one wonder how Symantec could have taken a winning system and broken it.
In any event, my thanks to phatman who put me on the right track: delete the users, assignments etc in the DLO server, set it up from scratch AGAIN and reconnect and it is now working. But again, why should I HAVE to do that??? It SHOULD be a simple install, set up and forget, like the Veritas version was. But its not and I am thinking of looking for a different backup option for my existing and new clients as this is unacceptable..
Thanks to all who assisted,
