I have a customer with an SBS 2011 server and windows 7 Pro client machines.
Its been in place for a couple of years with no problems.
Now they suddenly cant access mapped drives to the server, NAS box on the network, email and browsing are OK so the network is OK.
When this happens I check the services on the server and Group Policy Client has stopped, whereas it would normally say "started" it shows nothing and the only option seems to be to reboot the server as there is no "Start" option.
After reboot GPC then says started and everyone is OK for a couple of hours until it happens again.
Where can I look for a cause or has anyone else had this
