The past two days i have experienced an issue with my DHCP Server service just turning off! I am able to turn it right back on with no issue but some end-user who's machines were attempting to renew were not connecting. Rebooted the server last night verified all services started back up fine then this morning a few moments ago same issue. In the event log i am seeing an event ID 10020 (This computer has at least one dynamically assigned IPv6 address.For reliable DHCPv6 server operation, you should use only static IPv6 addresses.). We are not currently using IPv6. The id gives me no real reason and its IPv4 that is being affected cause the service goes off. Any ideas?
