If all of the addresses in the static pool have been allocated to connected VPN clients, the VPN server can't allocate an IP address, and the connection attempt is rejected.
If all of the addresses in the static pool have been allocated, modify the pool. Solution : Verify the configuration of the authentication provider.

And in many circumstances, one connection is all you need. This feature can be handy if you want to access your home computer from work, even if your home system isn't connected to an always-on Internet connection.
In this Daily Drill Down, I will look at the differences between a dial-up remote access server and a VPN server, the benefits of setting up your XP Pro machine for remote access, how to configure XP to accept incoming connections, troubleshooting, and security concerns. Why do you need a remote access server? A remote access server is a computer that is attached to a modem or the Internet and is set up to answer incoming calls and grant access to its own resources and those on the local network to which it is attached.
A remote access server is often thought of as being a machine running a Windows server product and the Routing and Remote Access Service RRAS , often with many incoming phone lines and a bank of modems. What you can do via remote access When you attach to the network over the phone lines or through a VPN, you can do anything that you would be able to do from an on-site computer that is cabled to the LAN, as long as your permissions are configured to allow it.
The big difference between a remote access connection and an on-site one is speed; at the physical level, the phone lines are a much slower means of transmission than the Ethernet used to connect computers on-site. Dial-up remote access server vs. There are advantages and disadvantages to each.
