hi,

I have a problem. I have two computers at home one is windows 7 ultimate 64 bit o/s and one desktop which is loaded with XP. The problem I am having is, I can VPN in to my work place using both 7 and XP, but can't RDP to my computer at work using XP. 7 works fine though I can RDP in and do all my stuff. When I try to RDP using XP It gives an error " This computer can't connect to the remote computer. Try connecting again, contact the owner of the remote computer or your network administrator". I am a domain admin. The only difference that I can think of in both the computers is XP has Microsoft essentials installed and windows 7 is brand new L/P got to install essentials on it.

Can you guys help please?

Is the machine at work a Win7 machine?  If so, is it setup to allow remote connects from computers running any version of Remote Desktop?

Did you update your RDP on the Win XP machine?  You have to have the most current version to connect to a Win 7 or Server 2008.

Are the two machines connecting from the same originating location?

yes. They both are from the same location. Here is the interesting bit. Same computer I installed XP on another Drive(dual boot) and tested it. I was able to RDP in straight away. I installed Microsoft security essentials on the XP computer(that I am having trouble with) that could be the reason.
Does my local firewall or security essentials block my connection after VPN in?

Extra information that might be handy to you
I am using netbox router

this is my ipaddress after I VPN in:

The only other thing I can think of is the local Windows firewall on the XP machine is a problem.  Your network VPN is working, else the Win 7 connection would also be failing.  As you state it is a hardware VPN and a machine works at your end, that leaves the culprit as the XP machine, not the VPN or the network.

you are rights Dr Ultima. I sent an email to Microsoft Security essentials. They advised to disable Microsoft essentials. restart the computer and try VPN in and then enable it. I tried it and it worked. I didn't find any logic in it but it worked.

MS Essentials messes with the built in Windows Firewall.  That doesn't surprise me.

ukitsme,

I am not Objecting to your closure method, but I do question it.  If the firewall was the problem, and if the Assist you credited (http:#a34191453) states the firewall as the problem (which it does), why do you see that as an Assist rather than as an Answer?
