I've installed MOSS 2007 SP2 on Windows Server 2008 Standard R2 x64. I am able to reach the Central Admin and SSP admin on the server itself - but not from any other machine.
The Web application is listening on port 50000 for the CA and 51000 for the SSP admin. I am trying to access the sites using the following URL: http://servername:50000
Both of these URL's work from the server itself - but i get a "This page cannot be displayed" message when I try to access from any other machine (logged in as domain admin). I suspect some kind of DNS or Alternate Access Mapping issue? When I do a nslookup for the servername on the client machine I get the correct (and only) ip of the server. Same results when I run nslookup on the server.
Bindings in IIS 7 are set to listen for IP * and port 50000 (CA web app) and 51000 (SSP admin web app) on the http protocol, and the host name field is left blank.
