No VPN at all here, just a slow dial-up internet connection.

I did use quotes in Google but I still couldn't find an actual description of it. Just a bunch of pages saying to make sure it is checked for certain VPN setups and various schools and businesses.

What is it and should I have it checked or not? Will it cause problems with dial-up (as I am experiencing horrible useage problems that my ISP can't seem to find)?

Anybody???

Thanks!
