Henry,

Make sure you have COMMTIMEOUT on the TSM Server set to a
high enough number to accomodate any Exchange activity
that may need to happen during backups. I would try setting
COMMTIMEOUT to 600 to see if that helps.

If that doesn't help... many times, "-50" errors mean there are
network problems. If you continue to see this problem, contact
your network group to have them investigate possible network issues.

If you are still seeing problems, please call IBM support.

Thanks,

Del
