Hello All, this is my first post and it's a good one!
Netbios over TCP/IP has been disabled in my work environment. We are strictly DNS.
I've been troubleshooting a domain trust issue with another company and was told netbios was the reason. Out of curiosity, I enabled netbios on my 4 DC's. I rebooted 2 DC's. 1 of which is a Global
Catalog and the other is Primary DNS.
Once they rebooted all my users could no longer use anything that is AD integrated. I couldn't even log into the DC's because it kept telling me bad password.
My coworker was able to somehow get into the Primary DNS DC and we disabled Netbios. From there things got back to normal.
Of course I'm freaked out because I don't understand how that could have broken DNS and AD!
Can someone shed some light on what might have happened?
