I create a new server 2012 r2 and install on it SCCM 2012 R2. When I sent and application it stuck in Waiting for content Message ID 10035.
On Active Directory Forest Discovery I checked Enable active directory Forest Discovery and also automatically create Active Directory site boundaries when they are discovered and Automatically create IP address range boundaries for IP subnets when they are discovered.
I never get a IP address range boundaries automatically, but I create two manually.
On the user computer in the ccmcache folder you get sub-folders named 1 and 2 but they are empty
