Apple Mac joined domain and inherited Domain Controller name!

Hi guys

We have resolved this problem, however I wanted to ask you experts how it could have happened.

Basically, a few days ago we connected the Mac Airbook onto the network. I then joined it to the domain. That's when everything on our Windows network went down. We later realised that the Mac's machine name was identical to our Domain Controller's name. Even when we took the Mac off the network and then restarted all of our servers, it had corrupted the Kerberos so Active Directory, DNS nothing was working. It was because somehow the password in the database and the one in AD had become different!

Can this happen? Plus, when you join a Mac to the domain surely if it had even the same name there would be an error message implying you can't join it due to the names being identical. Or is this a major flaw with Windows?

Thanks for any advice guys

It sounds like a Kerberos/LDAP setting which placed the KDC service of the Mac atop of Active Directory.  Without looking at the logs on the DC and the Console on the Mac, I cannot offer anything more than that.

Why join the Mac to the directory in the first place?  Especially a laptop, what happens when the laptops leave the network?  Aside of being able to use an Active Directory account and a mapped share, what is the advantage?

The only reason it was connected to the domain was to access network drives. Usually, the MACs pick up the network and without an issue they connect to the shared drivers etc. This time, it didn't until it got joined to the domain at which point everything went haywire.

Either way though, you're right we haven't trailed through the logs on the MAC but we have for the DC. But either way, your answer does shed some more light and puts me in the direction of looking at the MAC logs.

Thanks man.
