Hi, I have upgraded my NT4 domain (NTdomain) to AD recently (domain.companyname.com). All works perfectly the only concern is that the client machines got 'old' domain name but no new FGDN in the login screen. Is there any way to have AD (DNS) domain name there on the drop down list? or the logon box always shows only netbios name? regards, Jakub.

Thanks. We'll let you know when a new response is added.

I have never seen a way to force a FQDN to appear on the logon screen. If your AD structure is example.com, the logon screen will show Example for the domain name. The NetBIOS name is the only name that shows up.

    I agree with sonyfreek. Have user input on login and call it added security.

    Hi, Well... I cannot see even NetBIOS name of my new AD domain. All I got there is 'old' name of NT domain I upgraded to AD. My NT domain named 'NTCompany' has been upgraded to AD called emea.company.com so EMEA should show up in the logon box but it does not. Is there anything I missed during the upgrade? thanks, Jakub

    Try removing the client from the current domain. Then join it to the domain with the new name and see if the new domain name shows up.

    Hi, I tried it already, I had one machine in kind of test workgroup, I added it to my AD domain (I even removed all WINS from that box) using Network Identification Wizard with FQDN. It was properly added but logon box still shows old NetBIOS name. I just realized that AD works (for some reasnons) in NT4 emulation mode, anyhow I modified registry settings on my test machine to ignore NT emulation: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Netlogon/Parameters/NeutralizeNT4Emulator not sure if these problems are because of that...

    Did you setup your DNS structure prior to setting up the Active Directory environment? AD relies on it and actually requires it to make it work. You shouldn't need WINS at all once you upgrade all of your Domain Controllers to DCs and can totally disable NetBIOS if you want it to be more secure. Also check to see if your DC that you created for AD is running the PDC emulator FSMO role. SF

    When you start a client computer that is member of a domain, then the things that happens is that the client computer queries WINS (NT 4.0) or DNS (win2k and forward) to enumerate the doamin list. So you propably have an old record or object showing the old name. So check your dns, check your "DNS search suffix list" on clients and DC's and lastly look in AD for the old domain name using ADSI Edit (only if you're familiar with the AD object structure - you may damage AD)

    I'm inclined to agree with sonyfreek and jcan123... Sad to say, but if you haven't done a "visit every desktop" to clean up their expectations, you're likely to run into this sort of problem. I realize that what I said doesn't mirror exactly what they said, but the overall change from a "flat" environment to a tiered environment has its own share of difficulties - and we've just got to slog past each of the various difficulties impeding our respective progress.

    Since the logon dailog as well as the security box after login is controlled by the PDC emulator you cant see the FQDN of the AD Domain. But you can login with the FQDN directly rather then the logon dialog box. for example the user name text box you can use xyz@abc.com Hope this explains Jakub
