Terminal Services refusing connections.
Posted on 2009-07-15
We have an SBS2003 Premium machine that is running as DC, Exchange and SQL Server and ISA. We are preparing to upgrade to SBS2008 so i have had to reconfigure the network topology, we used to have a dual WAN setup with ISA, but yesterday i removed ISA and reconfigured the server to use a single NIC for Net access and Network. The second NIC is disabled within network connection on the server.
All was fine until i rebooted the server to complete the uninstall of ISA, the server has come back up fine, but i cannot get an RDP connection to the system. Any attempt is immediately rejected by the server, this is from both Mac OSX and WinXP client machines.
I can ping the machine fine by both IP and Hostname, so DNS seems to be functioning correctly. I can also browse shares e.t.c and access to the SQL database is fine.
I have done a port scan and 3389 reports open and reports ms-wbt-server is listening. I have also done a netstat on the server and it shows the something is listening on 3389.
I have tried initiating and RDP connection directly on the server to localhost/127.0.0.1 as well as ip and that also fails.
Interestingly all the Terminal Service controls in Services on the server seem to be grayed out, so i am unable to restart the service.
