The DSL is plugged into the uplink of the router. 4 computers are then plugged into the router's ports. Any single computer can access the VPN, but never more then 1 at a time. When a 2nd computer attempts to access, either it is denied or the 1st computer is disconnected. It is a CISCO VPN and the software is installed on each machine. It is a Linksys router (unsure what model - it is at a remote location). Our server is Win2003 w/a Cisco hardware firewall, and i am able to access it from secondary locations at the same time as other people at tertiary locations.

I presume that you are accessing a remote Cisco router via an IPSec VPN from your DSL location. I also presume that you have VPN clients on each pc and are trying to access the Cisco from each, probably simultaneously. This is likely the problem.
The Linksys router is not capable of hosting a VPN on the router. Replace it with a router that can (e.g. Adtran 2040 Enhanced or a Cisco 800 series - I am not sure of the exact number). Configure the Adtran to host the VPN to the Cisco. Retire the VPN clients on the network pcs. Now the IPSec VPN is based on the routers and all should work.

I dont think the problem is your router. Those linksys routers dont really do any packet filtering. My guess is the problem lies in the access restrictions on the Cisco VPN. I'm not exactly sure of your connection type, but the four computers on your router could be broadcasting the same IP, perhaps the VPN cant distinguish between the pcs on the network.

If your 2k3 server is going to be a VPN endpoint to grant access to the network, you're going to need to make some significant changes. First off, it will need to be the gateway device for your network. That's not a great idea, though, for obvious security reasons. You'll need RRAS anyway to make it a VPN endpoint but that really should be on a dedicated server. Next, you'll have to set the server to be a DMZ host in your router so that all traffic that hits the router is forwarded to the server. And you'll need to give it a static IP. Just assign it one one on the proper subnet but outside the DHCP scope. Or you can port forward the ports needed for the VPN -- check the VPN documentation in Help & Support; I don't recall what they are -- instead of making it a DMZ host. Ideally, you should have a static public IP address from the ISP. You can use a dynamic DNS service to keep track of the current IP address, however whenever the IP address changes the VPN will go down and will stay down for whatever the TTL interval is on the dynamic DNS service.

Your remote router cannot handle more than one connection at a given time. You need to upgrade your router with one that can handle more than one computer at a time. Make sure the router meets your user amount needs.

Looks like the computers need to be checked for individual IP addresses - each PC must have its own unique IP,
eg . 192,168,1,20 - 192,168,1,30 etc
Make sure the router IP is the same for each pc (Bottom line in config) eg - 192,168,1,1
Its not easy when you use multiple PC's-
I had the same fun running a cyber cafe with 8 PC's !!
