I'd find out which IIS application pool is using that much memory. appcmd is your friend. "appcmd list wps" will let you see what app pool each worker process belongs to. Here you see the worker process with Process ID 9180 uses 786,596 KB of RAM, so see which app pool matches it, and from there which site/application is causing the trouble (IIS mgr is also very helpful; powershell is pretty powerful too -- just "Import-Module webadministration" first). I would also look for virus protection that doesn't use anywhere near that much resources too (seriously, this is amazing) Thanks - How do i do the first part i tried CMD and also run but didn't work?????? I can log into IIS Manager and can see the Worker Processes and the application pools etc, but cant extract the data Im using Team Viewer and cant print screen What AV solution would you use in a server environment?
