New Post: Show Pending Updates Firewall problem

Hi,
I have a strange behavior. I enabled with the GPO the remote administration as also mentioned in this thread , but still Show Pending Updates doesn't work. In the client Firewall I can see the DCOM exceptions. So Report Now, Dectect Now, Show Current Logon User and Restart PC is working only Show Pending Updates and Install Pending Updates are not working.
What I made wrong?
THX for your help
