In most of the machines for some reason SMS Agent Host service is getting stopped, how do we prevent this ..? do we have any way to start the service automatically when its in stop state..? Kris

Hi, I would start by checking the event log to see what is written there, also the c:\windows\system32\ccmexec.log file for any errors. There is a hotfix that could apply. "The Systems Management Server (SMS) Agent Host service (Ccmexec.exe) stops responding on a System Center Configuration Manager 2007 SP2 client computer" http://support.microsoft.com/kb/2278119 Regards, Jrgen-- My System Center blog ccmexec.com -- Twitter @ccmexec

Figuring out the root cause is key as suggested by Jorgen as this is clearly not normal behavior. ConfigMgr itself can't restart its own client agent service so you'll have to resolve whatever issue is causing it to stop.Jason | http://blog.configmgrftw.com | Twitter @JasonSandys

WMI corruption, Cryto service error, many things can cause it to stop.http://www.sccm-tools.com http://sms-hints-tricks.blogspot.com

Are these workstations or servers? We had this issue mainly on servers and you would see errors in event logs simular to Description: Faulting application CcmExec.exe, version 4.0.6487.2000, faulting module 4ab33e4d, version ntdll.dll, fault address 0x6.1.7600.16385. The SMS Agent Host service terminated unexpectedly. It has done this 21 time(s). The following corrective action will be taken in 300000 milliseconds: Restart the service. but if it does it so many times it will stop restarting it. It ended up being a issue with the ccm_caltrack.dll. Per below article renaming this to .old stopped the service from stopping. http://social.technet.microsoft.com/Forums/en-US/configmgrgeneral/thread/2e2a45ad-781e-460b-9ade-e05b08427684
