Is this Mixed or Native mode? What happens if you try to manually install the client? is there any 3rd party firewall or antivirus that could be preventing the installation on these clients?Kind Regards, Tom Ziegler http://www.sccmguy.com | Twitter @Tom_Ziegler

Temporarily disable all firewall and antivirus on clients and server, then check the result.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Here is the solution. We are getting winhhtp errors. It means client is able to connect to SCCM Server and while downloading the client files it fails. it turned out to be proxy server which was monitoring all the internal traffic. We have excluded internal traffic from monitoring. Thanks alll for help
