[Update - TMG] Slow reboot after Service Pack 1

On a Service Pack 1 of Forefront TMG deployment I was surprised to notice that the servers become very slow when starting after a reboot for example.

In fact it’ll take around 10 minutes (for real) between the first ping and the availability all the services like remote desktop.

Without Service Pack 1 no problem weird... After a case support it’s seems that it’s a known problem Microsoft, unfortunately I actually not tested if the recent Update 1 solve it.

To check if you are on the same scenario here’s how to proceed:
1/ Restart the server and optionally grind and bear it :)
2/ Open the events logs and on the System node search for:
