RWW Setup Issue

Microsoft Windows

I'm having issues with setting up the remote web workplace.

I can connect to the "welcome" page but get a "cannot find server or DNS
error" message when trying to launch the remote web workplace page from a
remote computer. I can access OWA, the monitoring reports and help from the
welcome page. I can also make a connection to the server using the remote
desktop connection.

When logged into the domain on the LAN, I have functionality for all
services provided in the RWW.

Any help would be appreciated!
Have you forwarded port 4125 from router to the external NIC of the SBS
