client connect to the internet by NAT/Basic firewall, cannot get Windows Update

[mtczx232]

the XP client connect to the internet by RAS - NAT (w2k3). the RAS
machine have two NIC. one connect to router (that also have NAT) and
other NIC connect to the office network. (I not connect the router
directly to the Office network for some reason). the Basic Firewall
Option is not Checked!

I realize that some site cannot be access by clients. and I see that XP
client cannot access to Microsoft to get Automatic Update? why?

Though I doubt it, it could be related to the double-NAT. Try plugging
the XP box straight into the router and eliminating the Server2003 NAT.
If that doesn't work, look for IE/Firewall settings on the XP box itself.
