Proxy On OFF Switch with get current state v2

A useful vbscript  for Laptop users who work in and out of the office and are behind a proxy server when in the office and are not when out of the office. For those users who have difficulty changing the settings manually through internet explorer this script can save them and your helpdesk invaluable amounts of time and headaches.
This script detects the current proxy state and depending on that sate prompts you to enable or disable it.
It also auomatically closes IE so the settings take effect immediately and then re- launches IE with the new settings.
The only variable thats needs to be changed is on line 47
Replace <Domain Proxy Server> with the IP or name of your domain proxy server without the brackets <> eg. ContosoProxy:80
