Ever since I setup a new 2016 Server for WDS/PXE our event log has been filling up with this error which shows that for providers:
WDSMC, WDSTFTP, WDSPXE
This error keeps coming up saying "An error occured while tryingto create the UDP endpoint for (one of the providers) on interface (always an ipv6 interface, none of which are on this server). This can happen if the network interfaces was disabled or changed., or some other application is already using the port. The provider will not be able to receive request on this interface.
WDS/PXE both work, DHCP is not on this machine, but this error is showing up like 10 times a minute. IPv6 isn't even enabled on any interface on this server so I don't understand where these are coming from.
I've seen a proposed fix where you tell it not to listen for DHCP on port 67, but if I enable it it breaks the PXEboot for clients on this network.
