If you have installed CRM 2011 then you will often get this error. I thinks it due to some new performance checking functionality put into CRM 2011.
This problem is complaining that the user (service account) you have specified to run the CRM the CRMApp pools and the CRM services isn’t in the Performance Monitor Users group.
This group isn’t an active directory but it’s a group on the CRM 2011 Server.
I have fixed this problem a few times but I saw this blog post by the yellow duck guy !!! and he has some step by step instructions on how to add the user to the group
- From windows, go to: Start > Administrative Tools > Computer Management
- Select System Tools > Local Users and Groups > Groups
- Select the Performance Log Users. Then right-click on Performance Log Users and select Add to Group
- Click Add and select your service account
- Click OK to complete
