We have an exchange 2003 server running on Windows server 2003. The server is also one of two domain controlers in our domain environment. I is running GFI mailessentials, Mcafee Virus Scan, and Groupshield. Starting yesterday I started noticing that CPU ussage is going through the roof. When I look at the processes tab in task manager I notice that inetinfo.exe, and RPCServe.exe are using most of the CPU. Inetinfo.exe is looking to be the worst. Any ideas of what it could be?
