Remote Desktop on Multiple PCs

I have 3 computers on my home network that all use the same port. I would like to connect directly to one computer, instead of connecting to one and remotely connecting to another through that one! I was told to open another port, which I did through regedit, but can't connect remotely. Can someone assist me step-by-step please?

 

You could try a program such as www.logmein.com . That might fit your needs.

 

Thank you!

 

If you have multiple computers behind a router that are capable of hosting Remote Desktop sessions (i.e. they all run WinXP Pro), each needs to "listen" on a specific, unique port number in order for you to access each one from the outside world. WinXP Pro RDP listens, by default, on port 3389. You can leave one machine at that, but you must set the others to something different. You must use regedit to change a sub- key of this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

Scroll down to PortNumber and modify it to a different number-- even one digit different will work, e.g. 3390. AS ALWAYS, be sure you are comfortable making a change to your registry before proceeding. Setting a Restore Point before doing so would be advisable.

Now you must go into your router's setup and map a port to that machine. Having your individual PC's IP addresses hard-coded is helpful here, as a re-boot of the machine may change it's dynamically assigned address. For example:

Hard code an IP address of 192.168.x.y, where x is the number used by your router in that position, and y is a number higher than the number of devices hooked to your router (in order to avoid conflicts). In the router setup, map the port number you chose in the edit of the registry key to that IP.

Now, from the outside world, you must know your internet connection's current IP, which can be determined by various methods. There are progs that will track changes of dynamically assigned IPs and publish them to a webpage. Another way is to open two IM program accounts like ICQ and run an account on each PC, modifying the privacy settings to allow only those on your contact list to view your IP.

Having done the above, you must use the Remote Desktop client to log into your home machine using the following IP syntax: aaa.bbb.ccc.dddnpn, where aaa.bbb.ccc.ddd is the current IP address of your home internet connection, and pnpn is the port number you assigned and set up to forward to that machine. Even if you leave one machine's listening port at the default, you will still need to hard code its IP, forward the port to its IP and append 3389 to the WAN IP when you log in remotely.

To access other PCs at home, repeat the steps above, assigning different private IPs and listening port numbers.

It is possible to run concurrent instances of the RDP client, so it's feasible you could connect to more than one machine at home simultaneously, switching between windows as desired. Would probably be quite a performance hit across the web, though.

It may sound like a lot of trouble, but you'll only have to do it once.

You can do the same with RDT, change the listen por on each installation to a unique port.This page (toward the end) explains how to do it for another remoter program.

when you open remote desk top you have to define the port you want to use if you change the defaul

192.168.1.1:new port number
192.168.1.1:3390
