We have a single Windows sbs2008 server running exchange, which is working fine. We can connect to our server using remote desktop, but when we try to use OWA for e-mail and a remote session to our users desktops, we get the page cannot be displayed, and the logon page never appears.
I have checked that all the ports 25, 80, 443, 987, 3389 are all redirected to our server, so I dont know what has gone wrong to prevent this part from working.
the address https://remote.domainname.co.uk
works locally, but not from an external system.
This used to work fine, but I just dont know how to diagnose and trap the problem.
Can anyone help?
