Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

My network looks like this:

DC   - SERVER01  - Windows Server 2008 SBS
TMG  - TMG01     - Windows Server R2 Standard
NAS  - DATASTORE - Cisco NSS6000

All machines and devices are joined to the domain.

I can access \\datastore\backups from server01.

From TMG01 I get

Error code 0x80070035 The network path was not found

Using both the IP and the hostname.

The Samba logs from the NAS look like this:

I have tried removing the NAS from the domain, deleted it from AD, rejoined without any luck.

The NAS must be able to stay on the domain while this is working.

Using the traffic simulator I can use port 445 and it passes. Still can't access the NAS though. –  sam Jun 28 '11 at 20:50
    
rebooted TMG last night, now i can see the NAS. What the hell. –  sam Jun 30 '11 at 20:28

TMG is very locked down by default for localhost traffic (so much so that you can't even RDP into it). If you use the traffic simulator, it will tell you exactly why the traffc is being denied.

You will need to create a new access rule from Local Host to the IP Address of the NAS.

I have a rule setup to allow CIFS from the internal network to the local host, and another rule setup to do from the localhost to the internal network. Was this the wrong rule? –  sam Jun 27 '11 at 1:45
    
I have made a rule under Firewall policy that allows all protocols from Local Host to datastore, but it still doesn't work. I think I'm missing something blatantly obvious. –  sam Jun 27 '11 at 2:02
