file sharing - What can prevent a Server 2008 machine accessing its OWN UNC shares?

I need to set up a UNC share for my hosted dedicated server to access a share on itself. Unfortunately TFS requires a UNC share.

I am on a Windows Server 2008 Standard SP2 64bit dedicated server behind a PIX 501 firewall hosted with GoDaddy.

I just cannot get the server to access itself and get this error:

Windows cannot access \\SERVER\SHARE
Check the spelling of the name.. etc.

I've found numerous questions about this but no answer to my problem.

• Server 2008 Standard x64 SP2


• Workgroup - not domain


• Windows Firewall is off



• Computer browser service is on


• I am trying to access \\MYMACHINE\TFS-BUILDS by typing in - or double clicking. Neither works.


• Machine has single network card


• Filesharing wizard says share was ok


• Share was showing under 'Computer management'


• Permissions are set to 'everyone' full control


• No obvious errors in eventlog


• Reboot didn't fix it


• Unfortunately I cannot try to access other shares in or out of this machine because it is a hosted dedicated server and the only machine behind a hardware firewall.

The only thing left i can think of is that the hardware firewall needs to be configured. I don't think it is this because we have a 2003 Server machine behind a different hardware firewall and that one works fine.

What on earth is left?!
