Remote desktop web connection

HI,
I am trying to set up remote desktop web connection. So I can allow Admin's to remote to my servers from any web page on the internet.
I have installed the webconnection through IIS 6.0 on a server running Windows Server 2003 Standard Edition SP2.

I can hit the Remote desktop web connection page from the internet fine at http://tdms-tmuk.co.uk/tsweb

Both Port 80 and port 3389 are forwarded on the router to the machine hosting the service but when I type in either a server name, IP address or the external IP address of the domain I get the error message

"the client could not connect to the remote computer. remote connections might not be enabled or thecomputer might be too busy to accept new connections. it is also possible that network problems are preventing your connection. please try connecting again later. if the problem continues to occur, contact your administrator."

If i load the webpage from a machine on the internal network I can connect to the machine without any problems. I just can't seem to connect from the internet.

Any suggestions please let me know

There isn't anything restricting which IP addresses can connect anywhere is there?

Have you got a firewall in place that could be blocking these connections?

That was the first thing I checked. I have made sure that there are no IP restrictions on the firewall ata all and the ports are forwarded top the remote computer.

What about on the IIS website on the Terminal Services server? Does that have any IP address restrictions in place?

I have just checked and ISS is set to Grant Access to all computers on both the default website and on the TSweb folder from within that.

Can you see that the connection is actually getting to the Terminal Services server anywhere using logging on the firewall or something like NetMon on the server?

I have got around this by just setting up a VPN connection and using a standard remote desktop connection. this works far better.

Thanks for all your help
