I just confirmed that the server is actually a windows 2000 standard server running on a HP DL360 G3 dual processor server. Just wondering if this issue might be resources related. We have 2 72GB disks mirrored with 2gb memory. Our IS is currently 25GB , stm file 11GB. There doesnt seem to be much stuff out there relating to this issue and I am kinda running out of ideas. even thinking of a defrag to reduce the DB size.

Did you encounter any kind of issues when you installed SP2? Also, be sure that you don't have any anti-virus software running on your Exchange server that is allowed to scan the transaction logs. Things do not work well when AV is scanning a log while backup software is trying to commit it.
