DLINK DNS-323 NAS drive not detected.  Firewall issue.

If I disable Microsoft Firewall, I can connect to the \\ip\volume address manually to this NAS drive.  But I must have Microsoft Firewall on in order for ISA server 2004 to do its job and provide other essential services.  What rule can I add to ISA server 2004 to allow the server to conect to this network resource?

Just to clear a few things up, you are disabling windows firewall on the internal client that is trying to connect to the NAS inside the network on the same subnet?

ISA has windows firewall disabled as default on the ISA server machine and as such doesnt compromise the security of the web facing ISA server if the local client firewall is disabled. (However still recommend to keep it turned on)

Is there any error logs relating to the traffic to/from the NAS on the ISA logging?

Yes, router =, server with ISA nic is (other NiC (, NAS is  If I turn off Windows Firewall then a terminal server ( connected via a crossover cable to the other NiC ( can't connect to the SQL or other services on the main server.  So its a catch-22 until I find the path (rule) through ISA to enable both objectives.

Thx, Rich

Note its Microsoft Firewall, not Windows Firewall that is the key to this problem.  Disabling Microsoft Firewall service kills external RDP access to the server, but enables connection to the NAS, and vice versa.

Disregard this question.  I'll put the NAS on the internal network so I don't have to go through ISA.
