I have a Compaq Proliant ML530 running Windows 2003 Server and Exchange 2003. The machine has had the same 3GB of ram and nothing has changed. I have been experiencing random reeboots. Sometimes everyday other times it may run for a 3 or 4 days. Other than the reboots and bugchecks it runs great. I have attached a handfull of minidumps. Thanks in advance for your time and help.
