SYMPTOMS

A Windows Server 2008 R2-based computer that is running Microsoft Threat Management Gateway (TMG) 2010 stops responding for a period of time when the computer settings are applied at startup, or some of the Automatic services do not start after the computer restarts.


CAUSE

This problem may occur because of a missing service dependency that causes a deadlock condition in isactrl (mspadmin). When this occurs, isactrl (mspadmin) cannot set its state to SERVICE_RUNNING.

RESOLUTION

To resolve this problem, install the service pack that is described in the following Microsoft Knowledge Base article:
2555840  (http://support.microsoft.com/kb/2555840/ )  Microsoft Forefront Threat Management Gateway 2010 Service Pack 2

WORKAROUND

To work around this problem, change the HTTP dependency settings on isactrl on TMG servers. To do this, run the following command: 
sc config isactrl depend=RasMan/SSTPSVC/FwEng/ISASTG/bfe/mpssvc/HTTP

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

If you do not require SSTP-based VPN, you can help prevent the deadlock from occurring by using the registry change that is described in the following Microsoft Knowledge Base article:
2004121  (http://support.microsoft.com/kb/2004121/ ) Windows Server 2008 computers hang during startup while "applying computer settings" and services configured to start automatically fail to start
