I get the error message. Unable to add server. Node name wasn't found (2000).

There are other macpro's and imacs on this AD domain. I just have this one machine that I cannot join to the domain. Any suggestions?

    Hi this seems to resolved the same problem I had.

    1) Boot to Recovery Mode (Hold command-R on boot)

    2) Select Disk Utility and do a Repair Disk Permissions.

    3) Restart after disk permissions repair is complete

    4) Setup Active Directory without issue.

    Note: I tried to repair disk permissions while logged in under user under Disk Utility in Applications however this did not seem to fix my issue.  There must be a file open when logged in that cannot have it's permissions changed that is causing this issue with Active Directory setup.  The question is what file causes the issue and what changed it's permissions? Maybe an update to the OS on a software update??? who knows.

    Hope this help anyone having a issue with "Node name wasn't found" error.

    This problem is definately related to Lion. This macpro is a machine that didn't have any data on it so I wiped the hard drive and installed Snow leopard....I was able to join the domain. I then updated to Lion. Now I get a message at the log in screen that says network account unavailable, but once logged in with local admin account is shows the macpro is on the domain. I cannot log in using any network accounts. I am going to try the repair permissions option to see if that does anything...will update after.

    OK so i did the repair permissions and still no access to network accounts. I am scared to remove it from the domain and put it back because it may not come back. Any suggestions?

    Can you try the following?

    1.set the client's time to the network time from the windows server
    2.deleted the computer account off from the Active Directory
    3.restart the Mac client!

    Also can you verify this?

    Do you have anything other than letters, numbers, and underscores/dashes in the OS X machine's name? If so, you'll have to remove them before binding to AD. Also, you should make sure that the name is 16 characters or less

    Changed the time, deleted from AD, restarted....nothing changed. The computer name consists of 4 letters - nothing else.

    Ok, so I reset the time AGAIN and deleted the account off AD AGAIN. Then I unbinded it and then binded it again. Restart between each step. Now it's working.

    Thanks for the help!!!
