Within the last couple of days our Companyweb page would no longer show up on our client workstations here at home.
Nothing has changed, other than the fact that I have just done Phase 2 of a Swing Migration on this network. We have a new server to replace the ageing 1U that is currently serving our SBS needs.
I thought that it might have been TempDC's presence in AD and DNS that was messing things up. But cleaning out AD of TempDC's presence did nothing to fix it.
With the help of a tool called WFetch 1.4 which is part of the IIS Diagnostics Toolkit, and can be obtained here, I was able to figure out that I could connect to Companyweb when the tool specifically had port 8080 as the port to connect to.
I received a host not found error if port 80 was the port to connect to.
It has been a bit of a puzzle. The only other thing that I could think of that has changed was the update for the ISA firewall client to make it compatible with Vista. I am not sure if this is the culprit yet as I will need to test it further.
Armed with the above info, it came to me that when WFetch was directed to port 8080 it was being told to work WITH the proxy server for local addresses, and not BYPASS it.
I opened the Connections properties for IE's LAN Settings, unchecked, "Bypass proxy server for local addresses" and voila!
We now have our Companyweb back.
