A while back i ran into an issue where our local workstations could connect to our NAS drive at any given time. But for some reason during the evening our SQL DB backups were failing because it did not have access to the same NAS that i was connected to all day. I went onto our windows 2k3 servers and had no issue at all connecting, but as soon as i tried on windows 2k8 i was denied access.

What could possibly be different? Windows 2008 came out with alot of enhancements from stricter security policies to better performance monitoring. If you go to your Administrative Tools/local security policy click on Local policies then click on Security Options scroll to Restrict NTLM: Incoming NTLM Traffic and change to Allow ALL …… Also change Restrict NTLM: Outgoing NTLM Traffic to Remote Servers to Allow ALL. Try connecting to your NAS now. You should not be prompted for login credentials again.
