What are TCP Port 5445 and UDP Port 3935 used for on Windows Server 2016? [closed]

I’m facing a dilemma, I built 2 physical servers and for some reason for all the IP addresses assigned to that server it’s listening on Port 5445 (TCP) and also 3935 (UDP).

Applying the same configuration but in VMWARE, it doesn’t listen on these ports.

I’m trying to figure out why? It lists process ID 4 and the owner is “System” NT Kernal and System.

At first, I thought it was SMB2.0 and I disabled that via Registry, but it didn’t make a difference.

Any guidance on where and how to look will be much appreciated.
