When running the CTIW it does not pickup the router and give the option of typing the IP of the router and server in manually. Once this is done the wizard fails. UPNP is enabled on the router and the server is plugged in directly into the router. I am finding a few posts on the net with regards to anti-virus but the only software on the server is Windows One Care. We loaded the server at the office and the wizard did pickup a netgear router but we changed the IP range to 10.0.0.0 and when trying to rerun the wizard it fails.
