@Tom-Elliott
Thanks for your response (my english is not very good).
Yes we have high CPU usage since we have deploy the new client (0.11.9) with GPO.
We have try to modify FOG_CLIENT_CHECKIN_TIME but we think value over 60 seconds are no effects.
In our client log we see in general a contact server every 60-200 seconds.
We have more than 1500 clients.
If the problem is here is it possible to modify checkin time to 15 minutes ?
Or if the problem is not this where i can find informations for identify in detail the source of the problem ?
Regards
