I just set up a new SBS 2008 box which can't connect to its own RWW site. There is a GoDaddy certificate and it is accessible from other internal computers and from the Internet. It also will not attach to other RWW sites I tried but otherwise seems normal. It resolves the external address, there is a zone in DNS for remote.<domain>.com and of course, going to the IP address in IE gets the IIS 7 splash page. Any ideas? It's a problem not being able to use OWA while on the server.
I'll try a few other IIS7/RWW sites tomorow.
