Just finished installing SP1 for Server 2008 R2, all went fine other than i can't access any shares using a UNC. When using \server from clients or on the server i get the following message;
Windows cannot access \\ntserver Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose. Error Code: 0x80070002 The System cannot find the file specified.
I've also tried with the FQDN and the ip and i get the same message. I've disabled the firewalls on the server and client and still have the issue.
EDIT: also found these in the event logs, unsure if they are related;
The WinRM service failed to create the following SPNs: WSMAN/NTSERVER.school.local; WSMAN/NTSERVER.
Additional Data The error received was 8344: %%8344.
User Action The SPNs can be created by an administrator using setspn.exe utility.
The winlogon notification subscriber <GPClient> took 97 second(s) to handle the notification event (CreateSession).
I'm lost at what to try now!
