What IBM told you is correct. We found that our Norton AntiVirus code was breaking the inferface because it was hanging things up when mail was coming in at the time of the backup. What happens is the backup interface is hung open. The only way to clear it is to cycle the Exchange services tasks.
This problem is not limited to TSM. We saw it on NetBackup also. Paul D.
