I have VPN setup on a Windows 2003 Server. I can VPN in successfully, however, only 1 connection at a time can be made. If a second user tries to connect to the VPN connection, they get an error. It does not allow for concurrent connections. I've checked the settings on the server and cannot find any place to specify how many connections I would like to allow. I am behind a Cisco Pix 515e firewall. Not sure if that's what is causing the problem. Any help is appreciated.
