Okay on my SharePoint server, when i want to grant a user permission to lets say the Owner's group, i go and search for the user in A.D find Him, and when i add him i get this error:
Server error in '/'Application..
The same happens when i say select a user to view his permissions in SharePoint, i get the same service, also in IIS i had a look at the accounts that the application pools are using and they are a domain account with the correct rights to connect to A.D.
In event log this is the event.
