We are running Back-end Exchange 2003 SP2 on a Windows Server 2003 SP2.
The SMTP and IIS services are stopping about once every 2 minutes. We have both services configured to restart automatically.
This started on Friday evening about midnight for no apparent reason.
In the c:\windows\pchealth\errorrep\userdumps, files are appearing for w3wp.exe.
In task-manager,when things are running correctly, the inetinfo.exe process is using about 50 – 90% of the CPU resources.
We have stopped the services for Symantec Mail Security and GFI mail essentials and the problems mentioned above continue to happen.
