Ok you guys had to start talking about this and now it has happened to me. Nearly all my servers in prompt mode didn't take a backup last night. Nothing in the activity log and nothing in the dsmsched.logs. I'm running server 5.1.6.4 on AIX 5.1 and clients range from 4.1.2.12 to 5.1.5.15, all Windows (NT and 2k). Most of these servers had the MS patch installed for the blaster virus yesterday. Is this just a coincidence??. I know its not a network problem because all my UNIX clients where running backups all night and those are not scheduled by TSM but by crontabs.
So David, what was the tcpip settings you had to change?

They had me adjust the tcp values and the problem has not reoccurred. David
