I have tried everything that you have suggested. I have an active case with
Microsoft and Veritas. Neither know what is up here. I have all the latest
hot fixes, drivers and software. This has been a bad experience! I believe
the problem is with Veritas but I can say for certain I did not have these
problems with Exchange 2000. My backup environment has not changed since I
upgraded... Just the version of exchange has.

I just bought an ML 330 server with dual xenon CPU's and 4 GB ram. Maybe
that will help! When the 400/800 HP LTO tape drives are released in march I
will buy one!

Regards,
Scott
