Hello, I have a big problem here. Recently I had a problem with a Domain member, so I just changed it to Worgroup, and when I tried to join the domain again, it said "Active Directory Domain Contoller could not be contacted". If I use DHCP to obtain the IP address (client machine), it receives the correct IP address and DNS, but still do not join the domain. If I set the IP and DNS manually, still the same error.
What have I done so far? (probably forgot some)
- restarted every service (kidding, just netlogon, dhcp, dns).
- ping ok between dc and clients
- flushed dns / registerdns in server / clients then restarted dns and netlogon
- disconnected router from network and tried again
I would highly appreciate any help you can give me.
