After deploying a new vSphere 6 vCenter Server Appliance (VCSA) and configuring the Platform Services Controller (PSC) to act as a subordinate Certificate Authority (CS), I was unable to register the NSX Manager to the Lookup Service. Try saying that fast after a pint or two!?
Attempting to register NSX to the Lookup Service would result in the following error:
NSX Management Service operation failed.( Initialization of Admin Registration Service Provider failed.
