I’ve seen couple of forum posts in which people are getting problem with distributing packages to Windows Server 2003 (WIn2k3) ConfigMgr 2012 DPs (Distribution Points).So, thought of sharing the same as a blog post.
We should Enable/Install RDC (Remote Differential Compression) to successfully distribute the package to CM2012 DPs. Also, we should note that BITS Server Extension is installed on Win2K3 DPs (it’s not installed by default).
