unc

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. Is this possible?

Does 'UNC traffic' go out of the machine and then back in again?
