Problem

Users complain that they cannot connect to any network shares on your server. On inspection of the SBS2008 server, you may find you cannot launch Active Directory users and computers, Sites and Services or and other AD tools. Additionally this tends to happen every 7-10 days, but a reboot resolves the issue.
