We recently setup a new COmcast business internet account switching from Paetec. RWW and OWA no longer work even though the Comcast router is in pass through mode. I tried running fix my network and connect to the internet but neither seem to resolve the issue. The Paetec connection is still active. When I plug back into it, RWW and OWA work just fine. Is there something on my SBS 2008 server that I need to change? I am currently using the internal SBS firewall instead of the Comcast firewall which is off.
