Some time ago ​I found this very nifty tool while working with a customer; it is helpful in determining if GPOs are causing a slow logon time.

It needs to be installed on one of the VMs and it should assist you with setting up verbose policy for the logging, but if it fails to do so, these are the manual directions:

Define a value at the registry like this:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Entry: UserEnvDebugLevel
Value data: 30002 (Hexadecimal)

To make sure you have current log data, do the following:
Go to %systemRoot%\Debug\UserMode and delete or rename the current Userenv.log; Log off and log back on to reproduce the problem. A new Userenv.log will be produced.

I found once with this tool that this customer’s IE Branding policy took 14 seconds to complete, disabling it obviously accelerated the logon time.
