There are two Exchange 2000 Mailbox backups that basically come to a complete halt and don't finish. They start at a decent transfer rate then slow over a few hours.I have to kill them daily. The DB jobs for both of these servers run fine and these mailbox jobs used to run with no problems. The only thing I see is multiple (sometimes 20) bkpbar.exe running even when no backups are running. We have killed these and rebooted the servers a few times and the same problems keep coming back. There are 11 Exchange servers in the environment and these are the only two I am having problems with. Any help is appreciated. Thank you.
