I have a windows 2k3 server R2 configuerd as a domain conroller with 34 domain users in the active directory, on the DC Exchange Server 2003 is installed on the same DC. I have no backup DC, my network structure consists of only one Server.
Recently, domain users can not access mapped drives to the server or any shares. I can not add users to the domain when this happens. This issue happenes randmoly and wont resolve untill i restart the server. I suspect it could be DNS related.
