ok i got my proxy server to work last night, followed the instructions and everything down to a tea.
rememeber when you install something on vista run as administrator
also make sure u download the net framework 1.1 its vital then restart your laptop/machine.
make sure u have the make server download and the extended front interface.
and the ip has to be the one it gives u in ur cmd>ipconfig
its very very simple.
then its just a stage off manually going through ur internet settings until u get to the proxy menu and typing in ur ip address etc...
and hey presto works within 5 goes of bypassing normally first go
