Hi all i got several computer where when looking with client center, I am seeing Those are waiting sine last month...Is this another WMI issue?

I doubt it. WaitingEnvironment means there are rules within that particular advertisement for which this particular client hasn't hit the criteria yet. there are several possibilities, here are the two that are usually the first culprits the Program is set to run "only when no user logged in" the program is set to run "one when a user is logged in" Either way, until that condition is met; it won't run. It's also possible (I've seen in seldom, maybe 3 times, but I have seen it) where the program is set to run only when no user is logged in; but for whatever reason the trigger about 'user logged off' didn't register to the cm client. Usually just a reboot fixes that (and do NOT log in immediately; just stay logged off for a several minutes, and let the advert run).Standardize. Simplify. Automate.
