My Exchange 2000 SP3 Server running on Windows 2000 Server SP4 seems to crash occasionally overnight when running the Exchange backup. The server itself simply freezes i.e. mouse pointer doesn't move keyboard doesn't respond and it can't be ping'd. It always seems to be when the individual mailboxes are being backed up and NOT when the Exchange databases are being backed up. I am using a standard DLT drive shipped with the Poweredge 2600 (Dell Powervault 110T Drive).
Does anyone know why this is happening?
