    How many Domain Controllers do you have?
    Make sure they are all pointing to the same INTERNAL WINDOWS DNS server.

    Also check in Active Directory Sites and Services expand both DC's ad right click on NTDS Settings and make sure the check box for Global Catalogue is enabled.

    Then restart the netlogon service on each DC so it updates it's DNS records.

    Then run DCDIAG again.

    We have 3 DCs.

    They all use the same DNS.

    Should I check use GC on all DCs in sites and services.

    Yes check them all, if you only have a single domain then there is no reason why they cannot all be GC's

    then restart the NETLOGON service on all DC's so they update DNS with their correct records.

    Ok, this has been done.

    Any Idea, how long for things to catch up?

    thanks for your help.

    Few minutes at the most.

    Check your exchange server is using the same DNS server then give it a restart.

    None of your servers should have any external DNS servers in their network configuration.

    A reboot fixed the issue for exchange server login. now I've been having issues all day with time.
    Some of my server's wouldn't let me log in with Domain creds, because that servers time wasn't the same a our DC. Any suggestions.

    Thanks for all your help, all seems ~OK for the moment, my long range goal is to demote Cxxx and promote Nxxx as the primary DC.

    If you could look at one more thing for me. I was getting an error replicating From Nxxx to Delta and it mentions target acct name is incorrect.  Any ideas?

    I am now getting a clean DCdiag, any other tests I should run.

    Thanks again. Happy Holidays (not for IT admins, my busy time)
