The PLA service relies on the retrieval of several keys, at least one of which will have failed to result in the server failing to start with the error 7023: Access denied.

To identify the particular retrieval that fails:

  1. run process monitor (https://technet.microsoft.com/en-us/sysinternals/processmonitor.aspx),
  2. attempt to start the service,
  3. wait for failure and then stop process monitor,
  4. filter process monitor to only show ACCESS DENIED,
  5. now find the rows containing “PLA”

You will find a result along the lines of:

pla

To resolve, you must provide the appropriate access on this specific key in registry, so hop over to regedit, find the key, right-click and open permissions, and set.
