Increasing COMMTimeout from 300 seconds to 2000 seconds allowed the backup
to complete last night. However, about 5 sessions were lost and had to be
re-established to pull it off. I believe that there is a network problem
here, and I will be taking it up with our network switching guru when he
gets in.
Thanks for your help,
Rich
