I have this setup on my Home PC running XP Home SP2 to access my work PC. It was working fine until about a week ago.

The vpn connects okay, but the RDC says it cannot connect to remote computer. I have tried connecting to work from another computer at home that is on the same home network and it works fine. I have checked the settings are the same.

I have even downloaded the latest RDC program form Microsoft.

We had some problems with the home PC about a week ago. Is it possible some part of the RDC software has become corrupted. If so what should I do.

Thanks

Steve

It sounds like a software firewall problem, if other PC on the same network works fine...

I'd check new software installed since the last week, and check firewall rules to see if the RDC client is allowed to use the Internet.

Good question - you should know the answer. What have you installed on that PC since last week? Have you changed any firewall configuration? Have anyone else?

When you have teenagers - who knows what gets installed.
However I think I will work on the firewall. The Windows Security Centre is telling me the Firewall is on, but when I go to modify the settings it says it is off!

or try one of this off line tools

second
Remote Desktop Protocol (RDP) 5.1. need to be enable from your firewall

third
Port 3389 need to be enabled from your firewall

hope this will help you

A good place to start is going to system restore and seeing if any software installation restore points have been created, this will give you some idea of installations that have occured.

Resolved. was a dormant version of Zone Alarm, which was also conflicting with MS Firewall.

Thanks for the help.
