wire

I looked at the link and noticed that i have already open those ports via GPO.

Thanks I'll give it a try and reply.

As usual client installation problems, using push but the only way i can get this done is by disabling firewall on all machines. the machines are running windows 7. I created a firewall rule using AD to allow all necassary ports (4 TCP and 3 UDP) but i dont think that working. Another thing the MP is giving me this error every day (MP Control Manager detected DMP is not responding to HTTP requests. The http status code and text is 403, Forbidden.)and sometimes later in the day everything will be ok with the site error. WSUS will not install ( i'll retry the install and post errors) Thanks for all your help in the matter. PS. I did read many posts for help before posting.
