Question : VNC/RD access via VPN

I have a server running Routing and Remote Access, I also have remote computers that will connect to this server via VPN.  These computers will receive reserved IP addresses based on their unique userid/password combinations they have logged into the VPN with.  What I need to figure out is how to 1) List the active VPN connections, and 2) be able to remotely view their desktops from a third party computer connected to my server website.  I hope this makes sense, any help will be much appreciated.  If I need to clarify some more I will be more than happy to.  I am stuck so all help will be very much appreciated!

Answer : VNC/RD access via VPN

One option, since all users have a static IP, would be to manually create a list of users and IP's. Then add entries in the LMHosts file, using aliases and IP's for each user. These should not match any existing NetBIOS names. You could use city names, user names (not the same as actual), or simply a client number like A101. The LMHosts file would look similar to:

192.168.123.101    Bob
192.168.123.102    Joan
192.168.123.103    Texas
192.168.123.104    London

Presumably the person wanting to access the remote machine is doing so because they know the user is on-line. Once the LMHosts file is created, they can then just use the alias Bob,Joan,Texas... rather than the IP, to connect to the remote user.

If you need a simpler way to see who is on-line you could get an add-on such as Routing and RAS Connection Monitor, but this only shows the IP, so it may be confusing.

If you need more information on the LMHosts file I have a lengthy write up on my blog:
