cra5h0verr1de -> Edge Transport Installation error (8.Apr.2009 4:26:50 PM)

I have an Edge server in the DMZ with external DNS and Default gateway on the external nic and a hosts file setup with the hub server names and the edge server names A record in the internal DNS. Everything resolves Ok and the dns suffix is configured.
After running setup I get 1 error that indicates that TCP port 53 is not open or cannot connect to the dns. It is open.
Is this a normal error? I can ping and resove outside web sites like google and nslookup is good.

You talk about the external network card, is a different card used for connecting to the LAN ?
Since you can do nslookup's to the external dns port 53 is open on the external card so focus on the other card if th server has one.

Ahh the penny has dropped.
Yes I have an internal NIC (internal DMZ) with a static route to the internal LAN. I am not using DNS for internal resolution to the hub servers, I am using a hosts file. I have just realised that the Exchange setup must be looking for a DNS on the internal NIC and because I haven't defined one, this error trying to contact the DNS is occuring.
I would think in this case that is error message is normal.
Thanks very much for your view. Sometimes you just can't see the wood for the trees!
