Seems the first link goes to the second link.

I could not start with the second link solution because accesschk.exe is not recognized as a command.

:\Windows\system32>accesschk.exe -c mslldp
'accesschk.exe' is not recognized as an internal or external command,
operable program or batch file.

Yes the first link does as first gives details and the second one solution.
Accesschk.exe is a microsft sysinternals file, can be downloaded here:

I could not exactly follow the instructions.
1. The Windows Server 2016 is 64 bits so I had to start with  accesschk64 -c mslldp (did not need the .exe)

2. I was not exactly clear where to put the (A;;CCLCSWLOCRRC;;;SU)
accesschk.exe -c mslldp
  RW BUILTIN\Administrators
  RW S-1-5-32-549       <- these are server operators

1. Run: SC sdshow MSLLDP
You'll get something like below (SDDL language is documented on MSDN):
Four items listed in accesschk.exe -c mslldp but the divisions were more in SC sdshow MSLLDP using () to separate items.

Looks like four lines and some sort of closer.  Seems the (A;;CCLCSWLOCRRC;;;SU) should be before (A;;LCRPWP;;;S-1-5-80-3141615172-2057878085-1754447212-2405740020-3916490453)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD).

But the link says put in the middle of the last line.
That looks wrong.

Link says Take NT AUTHORITY\ SERVICE entry, which is (A;;CCLCSWLOCRRC;;;SU) and add it to the original MSLLDP security descriptor properly, right before the last S:(AU... group.  But did not get an S:

I decided to put the (A;;CCLCSWLOCRRC;;;SU) in front of the last line.
Which seemed to work.
