Thread: Answering Some Remote Desktop behind a router

Hello everyone,

My desktop PC having Windows XP SP3 installed at residence following a Linksys router. My roommate's PC is also having similar router.

I am attempting to attach to my desktop using Remote Desktop from a laptop that uses Wi-Fi. I would like to enable log in to my desktop using this laptop from my parents' place about 300 km from here. I have been attempting to get it going here before I leave and have been successful, except that each time my roommate turns on his PC/connects to the internet, it no longer works and I get following error message:

"This computer can't connect to the remote computer. Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator." This is without varying any settings in either my desktop or laptop from time it worked for me when my roommate's PC is not attached. My userid is permanently in field under where IP address goes on the RDC window.

I have port 3389 forwarded to my IP properly in Linksys admin page, and I have ports unblocked for TCP/UDP in my firewall settings on both host and client. Both systems have the ‘allow remote connection' checkbox checked in their system properties.
I am not definite what I should perform here. Any method I can log into Remote Desktop though my roommate is using the internet?

It should not create any difference when your roommate connects to Internet. I would ensure that for some reason you both do not have similar LAN IP address.

Hi,everyone

If roommate is off doing anything else and not using any bandwidth at all it rejects to let me log on.

I organized a static IP, similar as I had earlier when DHCP was enabled via the router, with similar subnet mask, default gateway and DNS servers at my ISP that I got from ipconfig /all on my system.

I attempt to modify port number for RDP in registry to 5-digit range, and included port to firewall exceptions with TCP, and modified it in my router port advanced settings.

Hi,

If you have allocated a static IP address and it is within Dhcp server's address range then it is feasible that other PC is dynamically getting similar IP address. Duplicate IP address will tap one or both PCs off the LAN.
