Hi, windows 2008 R2 + SCCM 2007 SP2 +r3 We are trying to push sccm client. out of 1200 machines, 400 machines install the sccm client well and rest of the machines get error as below. we have set the right permission on webdav.

Thanks kent. Above link we have tried.

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
