Shared folder DNS shortname "randomly" stops resolving on Windows Server 2008 R2

  • 772

I'm running your standard Domain set up - AD with DNS and a RDS server.

On the RDS server, I've mapped some drives to a local NAS using the DNS shortname...

\\folders\sharedfolder

\\folders is a static DNS entry on the AD server.

"Randomly" it starts throwing the error "Windows cannot access \\folders"

I can:

ping folders

nslookup folders (connects to local DNS server and returns the proper IP)

connect by ip address \\192.168.1.111\sharefolder

connect by FQDN \\folders.domain.com\sharedfolder

but I cannot use \\folders\sharedfolders again until I restart the RDS server.

net view \\folders = System error 53 has occured.

Thing is, I restarted the server Saturday afternoon for the problem and now it's Monday morning and right back to it!

  1. It sounds like you might have a GPO or other automated process that is changing the DNS Search Suffix. By default, when you do an unqualified lookup, Windows will try to append a domain suffix to it and do a lookup. It sounds to me like something is changing that suffix at an automated interval.
