We have a very strange problem we have just commissioned a new data server running Windows Server 2008 R2 (It is a VM running on Citrix Xenserver 6.0.2)
We have some Windows 7 x64 machines that refuse to connect to a single share on this server but only when the netbios name is used.
For example if someone from an affected machine tries to connect to
\\SERVERNAME\share$ they get an access is denied error
if they access \\SERVERNAME.domain.local\share$ or \\SERVERIP\Share$ they can access the share no problem. They can also access any other share from the server using a netbios name without issue (including if the same folder is reshared with a different name.)
The issue is PC specific and not dependant on who is logged in. Share permissions are all users Full Access and NTFS permissions allow everyone read/write access (which is verified by the fact it is accessible by accessing the same share but using the servers FQDN.)
The share in particular is being used for user accounts redirected folders (start menu, application data, desktop etc.)
For the moment I am updating GPO's to use the FQDN but to me this is working around the issue instead of resolving it.
