RDP 5 clients on Windos Server 2008
I have a new install of Windows Server 2008 Terminal Server and I am trying to get the client's thin clients to connect. I believe the thin clients are using RDP v5 and I can not figure out how to change the RDP level for the Terminal Server. When I go to make a new connection the drop down box is grayed out for "Connection type". How do I change this?

I changed those settings and the thin client is still unable to connect.
What error do you get when tyring to connect?
Anything in eventlog?
It can be a firewall issue blocking port 3389/TCP.

Don't see anything in the event logs. On the thin client it acts like it is trying to connect and the screen flashes for a milisecond. No error messages and no logs that I can find on the thin client. The thin client does show that it is using RDP5. It is a Neoware Thin Client, FYI. I can connect to the server from the XP worsktations and other 2008 servers so I don't think it is a firewall issue. I tried disabling the firewall and that did not help.
Any difference when trying to connect by using IP-address or servername with/without DNS suffix?

None work...
This forum thread sounds like the same issue. See if it helps to set 'Security layer' to 'RDP Security Layer' and 'Encryption level' to Low. If still problem, remove the TS role as suggested in thread and do the configuration before installing TS role to see if it works when running the server in 'Remote Desktop for Administration' mode. Make sure NLA requirement isn't selected.
