I have a client who has been accessing their work PC for a while now. The PC blew up and now they wish to access the server directly instead. I changed their port forwarding on their router to point RDP port 3389 to the server's IP, and they are an Administrator account in the domain (they are also a member of Remote Desktop Group). From within the company's LAN, they can use any XP's Remote Desktop to access their Local account on the server, no problem, but if they try to access the server's local account from their home PC, they can not even get the server's Window's Log on screen.
I began to think this is because their home PC's Computer Name is not a member of the domain, so I added my Laptop's Computer name to the domain's Computer List and tried logging in with my laptop, still will not work again, I can not even get the Server's log on screen. I'm running XP Media Center Edition, but would not think this is the problem.
When I attempt a login, I precede my log on name with the Server Name:
Can anyone shed some light on why I can not connect to the server using RDP from a remote location? Again, this Remote Desktop access works fine from within the company's LAN, and no, there are no other users open in Terminal Services on the Server. Also, there is just the standard two user simultaneous access on the server, there has never been any further TS set up.
Also, I can get to any other XP PC on the LAN remotely using RDP, if I set up the port forwarding.
I am sure the server's IP address is correct in the port forwarding, and like the other PC's I use only TCP, not both TCP and UDP.
Could it be that I need to open another incoming port on the router? Maybe port 443? I know I've seen this mentioned somewhere with TS.
