A single line of a logfile taken out of context does not help at all. It does not necessarily indicate a problem. So please add some details.

ok, i will share the log details, i am able to do patching in OS 2012, only issue is coming in Windows 7 VM Machine.

Same issue is shared on another forum as well.

Yes, I know this is an old post, Im trying to clean them up, did you figure this out, if so how? <o:p></o:p>

Thanks for reporting this symptom. We investigated and found that this error occurs when user unlocks the workstation. Due to this error, ccmexec service doesnt request for user required policies when user unlocks the workstation. We will investigate and address this symptom. Other than user unlock, all other user policy scenarios will be functioning as expected. The client will process user policies when user logs on as well as in the regular user policy polling schedule.

This discussion may  help. It did for me when I saw a similar patching problem, and that error in ccmexec.log.
