Q>> What is the WMI patch and what is it supposed to fix ?
A>> WMI patch replaces the Propalms Debug driver (DebugDrv.sys located under \Program Files\Propalms\WTS) with a WMI class component. 
        The WMI patch is supposed to fix stability issues where the Propalms Monitor service hangs or crashes causing it to go to the FALSE state on Propalms Console- Monitor - LoadBalancer page.
         It also fixes issues like Blue Screen of Death caused by the DebugDrv, when using Physical Address extension with RAM  in excess of 4 GB.
         Overall it will improve the stability of the Propalms Application role.

Q>>How do I know if the WMI patch has already been applied to my Propalms APP servers?
A>>  Things to look for 
          1) The DebugDrv.Sys file will be missing under the \Program Files\Propalms\WTS folder
          2) The file version for the files NMTSEManger.dll and NotificationServiceComponent.dll under \Program Files\Propalms\WTS folde would be 0.0.0.0.

Q>> How can I roll back changes made by the WMI patch ?
A>> There are two ways of doing it
        1) Uninstall Propalms TSE using Add remove Programs and then run the Propalms installer and choose the Propalms Restore Server  option.
        2) Undo each change manually,  a) Copy the DebugDrv.sys file back into \Program Files\Propalms\WTS folder
                                                        b) Replace the orignal  NMTSEManger.dll and NotificationServiceComponent.dll under \Program Files\Propalms\WTS folder and register it.
                                                        c) Restore registry entry for DebugDrv.sys file under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services to DebugDrv
                                                        d) Restart the server.
