Using a Windows Small Business Server 2003, Basic. Configured the Remote Web Workplace to allow remote admin and users to work from home. The server is not running ISA nor RRAS. This small office network is connected to internet by Dlink router on BT ADSL. There are port forwarders in the router for 80, 443 and 4125.
Worked fine for a week then suddenly stopped working. When trying to access the server, logging in as administrator, we get as far as selecting the server name and clicking the connect button. The following message appears :
VBscript: Remote desktop disconnected.. The client could not establish a connection to the remote computer.. blah blah.
Have waded through tons of useless standard troubleshooting steps found through google. The ports are definitely still forwarded correctly. Connecting by remote desktop (mstsc) both locally and remotely works fine. The remote web workplace connects successfully if run on the server itself. No clues are to be found in any of the logs.
I have used netstat -aon AND portqryv2 to check that nothing else is listening on port 4125.
Have used ping to verify that no MTU issues exist with the connection.
I have tried re-installing the remote desktop web connection component, restarting IIS and have run through the CEICW several times to no avail. The server has been restarted also.
We suspect that it is either the port being blocked on the BT ADSL connection (unlikely) or the TS redirector is malfunctioning. However I cannot find out whereabouts the redirector lives (it is not a service) and therefore am unable to check if it is running correctly.
Any further ideas will be greatly appreciated!
In anticipation of some expert assistance,
Ed Lockett
