Windows Server 2012 IPAM Error: Unblock IPAM Access

Received the following error when attempting to provision a server to be managed by IPAM:

Unblock IPAM Access

unblockipamerror

Firewall? Nope
Network Connectivity? Yep

Since IPAM is applied through Group Policy I thought to run “gpresult /r” and lo-and-behold the policies were not being applied to the server due to security filtering. Somehow the automated provisioning¬†task failed to add this server to policies security filter. Added the computer object to the filter and now IPAM is working.
