Enable and Disable Proxy Settings

Whenever I am working for a company installing there new Domain i get asked for a way to script the proxy Changes. this is so that the people using laptops can take them home and not have to go in to IE and disable proxy.

I have finally got round to writing a small VBS script to achieve this. This script is for to offices but can Easley be used for one office.

I have tryed this on Windows XP and Windows 7

            strGW = objItem.DefaultIPGateway(0)
			strIP = objItem.IPAddress(0)
			'MsgBox strIP & chr(13) & strGW
        Else
        End If
    End If
Next
'if you are in The office you will have the proxy Enabled
If strGW = Gateway1 then
	WSHShell.regwrite "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable", 1, "REG_DWORD"
	'MsgBox "Your are in Office One " & chr(13) & "Gateway: " & strGW
