I have a small network consisting of an AD domain controller, QNAP and ESX. I deploy my VMs using WDS. I found that some of my Windows Server 2008 servers, were unable to navigate to the QNAP windows shares either via mapping a drive or the UNC path, despite being able to ping and navigate to served web pages.

After a lot of hunting high and low, I found an article relating to something else (that I can’t find now) that suggested changing some GPO settings. Sure enough, on my Windows 7 laptop and the physical DC, the local group policy had these settings. After applying the GPO to the problematic servers the issue was resolved.
