SBS Server stopped accepting RDP connections

I use RDP to administer my SBS 2003 server. For a couple of years up until today it was fine. Today it is not accepting RDP connections. We also have a 2003 Terminal Server on this network. It is still working normally. When I switched on the SBS Server Console today, there was a balloon at the bottom right stating that an update had been installed which required a reboot. Maybe something happened because of this update.

I have rebooted the SBS Server and re-rerun the CEICW without any success.

What should I do next to try and fix this?

Perhaps you are no longer accepting remote connections?

Try:
windows key + pause/break
Go to the remote tab
Make sure enable remote desktop on this computer is checked

Any antivirus software or firewalls modified/installed on the server? You need port 3389 open to RDP

Nothing has been modified since it last worked. But I mentioned in my opening message about the update.

This Server has ISA Server installed. When I ran the CEICW I have checked the box to enable TS in the Firewall. I just ran it again without success

Try this:

1. Click Start, click Run, type cmd, and then press ENTER.

2. At the command prompt, type the following commands. Press ENTER after each command.

cd /d %programfiles%\microsoft isa server

regsvr32 wspadmin.dll


3. When you receive the DllRegisterServer in wspadmin.dll succeeded message, click OK.

4. At the command prompt, type the following commands. Press ENTER after each command.

md VPN\Netsh


net start fwsrv

Ok I did all that.....

The Regsvr32 command succeeded.

It said that the VPN\Netsh folder already existed.

It said that the fwsrv service is already started.

The server is not accepting RDP connections from the internal or external networks

Have you tried editing the system policy and adding your machine/ip address to the remote management computers group?

I shouldn't have to do that. I've always been able to RDP in from anywhere in the outside world. Ie from any machine and any IP address. Currently I am in the office and therefore trying to connect on the internal network. If I added my computer to that System Policy, it would not alter external access.

Also in the terminal server config, RDP-TCP settings under the network adapter tab make sure only your internal adapter is selected

Ok we have a partial success now. In the RDP TCP Settings, it was configured for all adapters. I changed it to just the internal adapter. Now I can connect from the internal network only. But this is what I would expect from disabling the externla adapter,

So how do I make them both work?

I just checked the RDP TCP Settings on another SBS Server that I adminster at another company. This server is working normally and accepting both internal and external RDP connections. The RDP TCP is configured for all adapters. So presumably my server should be able to function similarly?

Obviously we have fixed something by changining this setting. But i need it to work on both adapters.

I'm afraid I'm out of ideas then, I'll have a look on some of my virtual machines and see if I can replicate your problem.

Thinking that I might have flushed out a gremlin, I put the RDP TCP settings back to 'All adapters', but RDP stopped working internally again. Thanks for our efforts so far,

Later that day, I tried again to RDP into the server and it worked. So I don't know if it freed itself up, or something eventually happened as a result of me changing the RDP TCP setting. But i'll award the points and thank you for your efforts.
