Make sure there is a AD site that has the IP subnet of the exchange server

Then you should be able to run
Nltest /dsgetsite
On the exchange server and it will return an AD site name.

So if the exchange server has ip address and subnet mask of then you should have an AD site (let's call it HQ) that has the subnet defined

Then if you run the Nltest command I mentioned earlier, you should get an answer of HQ

Nope, that looks good, then on the exchange server in the application event log you should get an AD Topology discovery event to say it found a site to be in
