My setup: WS 2008 R2 DC server with Exchnage 2010 SP1 UR2 (MBX, CAS, HUB roles) and FPE 2010 HU2 installed. After restarting the OS, some services cannot autostart. System log contains: A timeout was reached (30000 milliseconds) while waiting for the Net.Tcp Port Sharing Service service to connect. -- The Net.Tcp Port Sharing Service service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. -- A timeout was reached (30000 milliseconds) while waiting for the Microsoft Exchange Address Book service to connect. -- The Microsoft Exchange Address Book service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. -- A timeout was reached (30000 milliseconds) while waiting for the Microsoft Exchange Anti-spam Update service to connect. -- The Microsoft Exchange Anti-spam Update service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. I've tried many things, and only uninstalling SCCM 2007 R3 Client fix my troubles. My SCCM environment is configured to auto install SCCM Clients, so after some time, SCCM Client installs again on my Exchnage server and those services can't autostart.

No, I'm the person in my company who responsible for solving IT problems like this... Please excuse me, but I find what this problem appeared even after complete SCCM Client uninstall, new automatic installations are disabled. When, i've uninstalled SCOM Agent, and the problem disappeared...
