All of my servers are built to a uniform standard as far as hardware, disk space, memory are concerned based on the roles that will be assigned. This weekend all three of my servers that run Exchange 2003 sp2 crashed. Other than running Exchange, these three servers have two distinct differences from the rest of my server population. They are running Trend ScanMail for Exchange and McAffee AntiVirus with the proper exclusions to protect Exchange. Event Log has the following entry: The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0x00000000, 0x00000002, 0xb458fdfe). A dump was saved in C:\Windows\Memory.dmp. I have attached minidump file. Nothing else in Event Log gives me a clue as to what is causing the crash. Any help reading the dmp file would be greatly appreciated.
