Ok, this is my tests:
1. Open the web from an external computer (through ISA) and open the remote
web workplace
2. Click on the "Connect to server desktop"
3. Select a computer and click connect
4. a popup error appear "Remote desktop disconnect", and I've the 4 possible
reasons
5. I don't click on the OK of the popup
6. At the SBS server level, I open a command prompt window and I type
netstat -aon | find "4125" and I see the port 4125 in listening mode
7. I click "OK" on the web, and the port 4125 is closed on my server

Second test:
1. On my server I open the Winsocktool and set it to listen on port 4125
2. on my external computer I execute telnet <external IP> 4125 and I'm
connected
3. I can type and transmit data from the 2 computers through ISA without
problem.

So, any idea?
some of my tests demonstrate that my ISA Server can create the bridge, but
with a remote desktop connection, this doesn't works.

Does I must install the firewall client on my SBS server ? (actually in a
securenat mode)
In the past, before installing the feature pack 1 of ISA Server , all works
fine.

Thanks for your help.
