Just took over managing a network for a company that has had 3 different companies managing it in the past year. Two servers and 9 PCs with an SQL DB hosted on one of them. The entire network had the firewalls turned off and a bunch of group policies defined to limit traffic. All of this because apparently they didn't know how to enable a few SQL ports through the server and workstations.
I have tried removing all the policies I can find, turned the workstations firewalls on again but I am having issues with not having the ability to RDP to any of the workstations. I can RDP to the servers no problem. Have checked the workstations to make sure RDP is enabled and the firewall rules allow it as well...no luck.
Previously the owner could remote straight in to their workstation from home using the full machine name plus :3390 port at the end. (Yes, they were natting apparently through the sonicwall.) I removed all the sonicwall rules and redefined them all to push 1723 and 3389 to the VPN server and established the RAS service on that server. They are no longer able to remote in, even with the port definition removed.
I can RDP into the servers but upon attempting to RDP from the servers to the workstations, this internal RDP does not work either. Need help on where to look for what is stopping the workstation RDP function.
