I noticed packages were not distributing to one of the Server 2012 R2 SCCM 2012 distribution points. The packages had failed. When checking the distmgr.log on the primary site it showed a few errors such as:

cWmi::Connect() failed to connect to \\DP.domainname.com\root\MicrosoftIISv2.2. Error = 0x8004100E

ERROR DPConnection::ConnectRemoteIISManagementWMI() – Failed to connect to DP.domainname.com error = 0x8004100e

For some reason IIS 6 WMI Compatibility was not installed on the distribution point. Once installed, I did an iisreset, redistributed the packes and I could see the packages distributing in distmgr.log

Here is a screenshot of it once it is installed:
