VBScript to change the proxy settings if disconnected from VPN

When connected to VPN, user's IE proxy settings get changed and is forced by VPN.
Often the users might get disconnected from VPN while working from home and this does not revert back the proxy settings to the original one.
I have written a VBScript to change the proxy settings of the users. This script can be made a shortcut and then used.

Option Explicit
Dim valUserIn
Dim objShell, RegLocate, RegLocate1
Set objShell = WScript.CreateObject("WScript.Shell")
On Error Resume Next
valUserIn = MsgBox("If you have been disconnected from VPN and want to reset your proxy, click Yes and restart Internet Explorer",4,"Proxy Reset")
If valUserIn=vbYes Then
RegLocate = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer"
objShell.RegWrite RegLocate,"","REG_SZ"
RegLocate = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable"
objShell.RegWrite RegLocate,"0","REG_DWORD"

'Enable AutoDetect in the proxy by calling this sub
IEautomaticallydetect

MsgBox "Proxy is reset to AutoDetect"

else
'I do not want any proxy so I have disabled this, but if you want to set a proxy then you can use this.
