Remote Desktop connection (RDC) Stopped working and I can't get it to work again

I have a windows XP PRO PC that was using RDC without any problems for many years and then recently  the PC got infected with a couple of adware programs that have been removed and since then I cannot connect remotely to this PC no matter what I try.
I had some problems with uninstalling some programs while taking care of the infection and eventually had to remove and re-install ".net framework 1.1 through 3.5" and Windows live Onecare.
So since the PC has been clean it's a NO GO for RDC on the PC.

I've changed RDP port numbers, checked the firewall settings, I've even tried connecting to it using telnet but something is keeping me from connection to it.
I do get a reply when I ping the PC and I can connect from the PC to other PCs using RDC.
I already have the usual configured (ie. added the users under the remote tab in system , allowed remote connections to the PC, etc.) as I mentioned the connection worked perfectly for years.
I've looked for answers but have had no luck.
Any help would be greatly apreciated.
Thank you in advance.

Can you please verify if  all services set to "Automatic" are running? if not which services are failing to run?

First off youve change the RDP ports?
You must change your router settings and port forward the ports to your ip address of the pc you are trying to remote in to.
Default is 3389. please port forward that to your pc's ip address.

Hello all,
Thanks for the quick reply.

panky23-- yes, terminal services service is set to auto what other services should I be looking at?

Manoj_a-- I'll take a look at the article and will give it a try.

iamshaked-- it's not a port forward issue , when I changed the ports I also configured them accordingly on the router/firewall. Originally when it was working (3 plus years) i had the default port changed to 8787 and the proper config. on the router/firewall. The issue started without any changes done to the router but to troubleshoot I reverted the port back to the default 3389 and made the proper changes on the router/firewall as well and i still cannot connect.

Thanks guys.
Seb

Hello Manoj_a,

I looked at the link you provided and I've already determined that I cannot telnet to this PC so it doesn't help me.
Thanks for trying.

Do you possibly have a nvidia video card? ive seen some drivers from nvidia that did not allow me to use rdp at all. Might want to look into that.
Is there any software that you can think of that would block ports or something
Windows live Onecare?? check there, spyware doctor if you have that, or possibly look into windows firewall if you havent yet.

Hello  iamshaked,
Not sure on the video card but I'll check.
no new software has been installed so no issue there and I've already checked the windows live one care (removed it and reinstalled it as well) to see if it's configured properly.
no other spyware software installed other than liveonecare.
Windows FW is disabled due to liveonecare but I checked and no issue there.

Thanks for the hints.

Hello all,
Resolved the issue by removing the port forward on the router/firewall and reconfiguring it again as well as on the Client PC.
Once that was done things went back to normal.
Thanks.
