Turn proxy settings on and off script.

Is the script meant to be a simple toggle every time it's executed or is do you need a trigger?

I personally use a script on my laptop that when executed, detects which network I'm on by serching for a server, then sets network shares, installs printers, sets proxy, etc. based on which network I'm on.

I might be able to help.

What I used before I started playing around with VBS was two .reg files that I shortcut'ed to the desktop. "proxy.reg" and "noproxy.reg"

"proxy.reg" substitute "ProxyServer" data with your (proxy IP address):(port #)
---------
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"ProxyEnable"=dword:00000001
"ProxyServer"="192.168.10.10:3128"
"ProxyOverride"="192.168.*;"

"noproxy.reg"
-------------
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"ProxyEnable"=dword:00000000

just copy the relavent text into text files and rename with the .reg extention.
Click on the one you want to apply, it may ask if you want to apply it to regisry, click yes.

If you'd like, I could whip up a single vbs script that would toggle on/off when you execute it. Let me know.

Copy the following text to file and name as *.vbs. I hold no copyright for this, so share and modify as you like.

Option Explicit
Dim WSHShell, strSetting
Set WSHShell = WScript.CreateObject("WScript.Shell")

'Determine current proxy setting and toggle to oppisite setting
strSetting = wshshell.regread("HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable")
If strSetting = 1 Then
NoProxy
Else Proxy
End If

'Subroutine to Toggle Proxy Setting to ON
Sub Proxy
WSHShell.regwrite "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable", 1, "REG_DWORD"
End Sub

'Subroutine to Toggle Proxy Setting to OFF
Sub NoProxy
WSHShell.regwrite "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable", 0, "REG_DWORD"
End Sub
