Management Point Affinity in ConfigMgr 2012 R2 CU3

Sometimes there are multiple Management points installed for high availability or communication reasons. With Distribution points you set boundary groups to decide with one to use. With Management points they will be randomly selected. This can be seen in ClientLocation and LocationServices logfiles. With Cumulative Update (CU) 3 however there's a possibility to set the Management point also. In this scenario you have MP1 and MP2, where MP1 is forced (for example). Let's have a look at the logfiles after applying the key:
Key: HKLM\SOFTWARE\Microsoft\CCM:AllowedMPs
Type: Reg_Multi_SZ
Value Data: <Management point>

-Rotating assigned management point, new management point is: 'MP1'
-Assigned MP changed from 'MP2' to 'MP1'
This will be applied daily. (every 25 hours)
-The MP name retrieved is 'MP1'. MP 'MP1' is compatible
-The MP name retrieved is 'MP2'. MP 'MP2' is compatible
-Retrieved MP 'MP1' from Registry
-Attempting to retrieve lookup MP(s) from AD. Lookup Management Points from AD: 'MP1' and 'MP2'
-Not persisting assigned management point 'MP2' because it is not in the list of allowed MP's
-MP list is forced, ignoring MP 'MP2'
-Default Management Points from MP: 'MP1'

This can be handy when you want to enforce Management points for static systems. For roaming systems this is not recommended, because it will still be communicate with the Management point, even when on another location. Still great to see that Management point can be enforced, when no use of a Secondary site is made.
