Web Server For remote Access

I have a few clients that use Windows Workplace (part of SBS2003) for accessing there servers and workstations on the network. What i am looking to do is Create a virtual Linux web server that can serve this same purpose. I would go to http://address and there would be a login.. and from there i could see the computers on my network and select them for remote control? has anyone see this before? or point me in the right directions.. i am new to Linux but im comfortable working with it...

Any help would be great!

Thanks

Chris

i do this, but i use hamachi. if you install hamachi and have them all join the same group and create a "virtural network" . Then run gHamachi (look in the hamachi forums) for a GUI. In this you can right click on any of the servers and "control using VNC" you can do this from any type of machine.
