I have recently upgraded from SBS 2003 to a new box running Server 2012 R2 as a Hyper-V host, with several VMs running Server 2012 R2 and one running Server 2008 R2 and Exchange 2010 sp3. We still have a legacy server runnning Server 2003 R2 64-bit as a Terminal Server, but it really now has only one remote user that accesses it.
I recently turned of the old SBS box, after the migration and demoting from its DC role.
The TS is no longer accepting RDP connections. I suspect that thew two things could be related, but I am not sure how or what to do to troubleshoot it.
I had changed the RDP port and it has been working on the non-standard port for years. I have checked the port setting in the registry and it is still set correctly. I have checked the Port Forwarding settings in the router and it has not changed.
I cannot even RDP across the LAN from another workstation.
I can ping the TS across the LAN and I can connect to other servers ok.
The TS only uses the Windows Firewall and I have tried to connect with the Firewall turned off, but I still can't connect.
So, can anyone help me to get this sorted?
I plan to replace the TS box with another VM, running Server 2012 running RDS. So it might just be better to forget the TS and get the new server working. I haven't done this before so any pointers in that direction might be helpful. At this stage I basically just need to get one remote worker access to the system again, as quickly as I can.
