Let’s say you are a network admin in charge of 4 servers located at a remote ISA protected site. You want to be able to connect to them all at the same time.
No problem.
First of all I’m going to show you how to have the RDP service on each machine listen on the standard port of 3389 and also on a different port.
First of all you have to open up regedit on each machine you want to modify. Browse to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Terminal Server\WinStations\RDP-Tcp]

Right click on the RDP-Tcp key and export it to somewhere handy, say to your desktop and open it in notepad or your favorite text editor.
There are 4 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Terminal Server\WinStations\RDP-Tcp] entries in there, change all of them to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Terminal Server\WinStations\RDP-Tcp2] and save the reg file then import it into your registry on each server you want to modify.
Now you should have 2 RDP-Tcp keys.

Highlight the new key and scroll down to the PortNumber dword. Change it to any port you feel like using. For this tutorial, I will use 30000 – 30003 for the 4 machines.

Restart the machines and they will all be listening on the different ports.
Now on to the target server’s ISA.
We need to create 4 new protocol definitions and server publishing rules for the receiving RDP machines.
Start up the New Server Publishing Rule wizard. Call your rule what you want.

Click next, then enter the Server IP address.

Click Next to get to the Select Protocol page, select the New button

Call it what you like.

Click Next. Select New.


Click OK, then next. No secondary connections. Click Next. Click finish.

On the select protocol page, the protocol will have been entered automatically.

Click Next. Select the listening network object.

Click Next, click finish.

Click apply to activate the new rule.

Repeat that as many times as you have servers to publish.
Now onto the Source network rule and protocol
Start up the New Access Rule Wizard on the source network ISA.

Click Next, and allow the new rule.

Click Next, and change to Selected Protocols. Click the Add button.

The Add Protocols box will pop up, click New, and select protocol

In New Protocol Definition Wizard enter a description, Click Next.

In the Primary connection window, click new.

Enter your port range.

Click OK, Click Next. No to secondary connections. Click Next.

Click Next, Click Finish.

Back in the protocol window under user defined, you can select your newly created protocols. Click Add.


On the Access Rule Source window, chose whichever object you prefer. For this tutorial I will use the internal network. It could be a computer object or IP range however.

Click Next. In the Access destinations window, select your destination object. For this tutorial I have used the External network object. This however, could be a single computer object, a range of IP’s or even a domain set.

Click Next. Select your user Set.

Click Next. Click Finish.

Click apply to activate your new access rule.

That’s the ISA parts done.
Now onto the RDP client part.
The entry in your RDP Client properties should look similar to this.

When you click connect, you should have a successful connection.
Modify your RDP client properties for each server you want to connect to and save them somewhere convenient.
