I'm quite new to ISA-Server, I have one as just a Firewall between internal and external.
Now I tried to realise a DMZ with ISA, but I won't get it running correctly. My Main-Problem is that I can't connect from internal to DMZ with RDP.
On the ISA I have 3 NICs (Internal, External, DMZ) and for each NIC a Network configured on ISA (Internal-->Internal,External-->External, DMZ-->DMZ). I have activated Routing between Internal and DMZ. And created a Rule to allow RDP between Internal and DMZ.
Now when I try to connect with RDP I see in ISALog one Initialized Connection and some seconds later, disconnected Conntection. Nothing else between the two entries.
So RDP-Connection is not established, can someone tell me where the problem is or is it just impossible?
I'm sorry if I forgot some important infos, or I wrote too complex.
Thx for your help ZeroCool

but do u have another solution for me? should I create just a set of computer or a Adressrange? with a range for internal network and a range for the dmz, so I can expand the preconfigured internal network with the dmz.

Hi I assume that you have Enabled RDP on the server in question
If you have multiple NIC on the server in the DMZ, Make sure it is set to Listen for RDP on the Appropriate NIC instead of All NIC's Go to Run-> tscc.msc -> RDP-Tcp Properities & navigate to Network Adapter Tab
I can connect with RDP from internal to ISA and from ISA to DMZ, so I think there is a routing issue on whole ISA or just in RDP. And the strange thing is, I can see a Connection Initialised and then a Connection Disconnected entry in the log.
