DHCP clients cannot see the domain (Windows 2008), DNS problem?
Hi everyone,
Help urgently needed - my phone keeps calling and I have no idea what to do next!
Something went wrong with our DNS server (Windows 2008 SP2).
DHCP clients can no longer login (domain is unavailable), workstations with static IPs work fine.
Here's output from dc1 (DC + DNS + DHCP server) ipconfig /all and dcdiag /testdns.
Looks like something is wrong with the DNS, I don't know how to fix it :(
Thanks a lot, you are saving the day!
