KMS server. How to fix the situation?

Question

System administration

Began to put in order, Windows licensing, which was inherited. I started by executing the command nslookup -type=srv _vlmcs._tcp.domen.local
And then I got excited: SRV (_VLMCS) records turned out to be 20 pieces. Only one of them pointed to the correct server, which is KMS. All others are workstations. I understand that they appeared from some kind of incorrect activation, or activation with the wrong key. What can be done about it? How to fight and correct the situation?

Tell me, direct me, for the first time with such a ..... I'm stumbling :(
