I have two Win 2K8 R2 Domain Controllers and a Win 2K3 sp3 DC in my test domain. I also have setup a one-way trust with an account domain.
If I connect to a memberserver in my test domain with RDP I can use an account from the trusted domain. It takes a long time but after two minutes I get the desktop. In this way I can only use the allowed two administrative connections.
Because I need more connections I installed the role Remote Desktop Services on a member server. I also installed a RD License server and added 5 user CAL's to it.
Unfortunately I cannot logon to this RDP server with an account from the trusted domain. It fails with a message "The specified domain either does not exist or could not be contacted". I checked the DNS on my test domain controllers. The Win 2K8 R2 DC's have conditional forwarders defined to the account domain and the Win 2K3 SP3 DC also has forwarders defined for the account domain. The RD server has two DNS configured (only the Win 2K8 R2 DC's). I also disabled NetBios over TCP-IP.
The production domain consist of three Win 2K3 DC's and one W2K3 terminal server. This domain has a one-way trust to the same account domain. I don't have the same problem there.
Two questions:
1: why is RDP logon so slow if I use a trusted domain account?
2: why is it impossible to logon with a trusted account when RD services are installed?
Thanks in Advance.
