Looks like there is problem with DNS server. Can you tell me please if you changed something in IP address configuration durung that maintenace window?

Can you post here results from that DC of

ipconfig /all
dcdiag /e /c /v
repadmin /showrepl /all /intersite /verbose

Regards,
Krzysztof

You may also consider rebooting this Domain Controller again. Maybe that simple step would help?

OK, so this looks like DNS problem on that DC.

Please review your NIC configuration in DNS section. If you have redundant DC with DNS, please reconfigure your DCs

As Primary DNS server use another DC in a network
As Alternative DNS use DC itself

do the same changes on another DC(s)

This should prevent similar situation in the future. Thanks
