Hello Stephan,
thanks for your quick replay. I'm at the last days not in the office, sorry for delay.
As you proposed I enabled the log and here is the result.
I saw there is an error by not to reach the update sites, but the system we use is a closed systems, the users are not allowed to go to the Internet. I hope this is not the reason for th problem?
