While configuring a SCCM 2012 R2 server I noticed some Critical errors in the Site Status.
After some investigating I found the problem how to fix this. You must add the SCCM service account and the computer account(s) to the local administrator group of the site server.
Go to the local users and groups and add the SCCM service account and the computer accounts to the the group. (You manually have to tick the computer box to enable to add computers)
When this is done you noticed that the services are on green again :
