Hide other domains from drop down box.


I want to know if it's possible to hide other domains from the drop down box at the login prompt.  We have a scenario where we have a subdomain that needs to be part of the same forest as other sub domains and will share some of the same resources such as exchange and some sql servers in the root level domain but users in london domain are not allowed to drop down the domain box at login to see the New York domain for example and vice versa

I don't think this is possible.  There is no problem with leaving it - unless the user has an account in the other domain, they can't log into it.

Hi i_campbell,

just to add my two cents, we have just configured a pretty crazy domain structure and i know of absolutely no way to hide domains from the list, if anyone does i will be very keen to know how :)

For legal reaons we have to stop a user from one domain logging onto a computer in the other domain by selecting their login box.

What about with by setting the DefaultDomainName registry value as per http://emea.windowsitpro.com/Article/ArticleID/47055/47055.html

I know this makes it appear in the box but can you restrict the other domains from showing?

I would do this by stating what machines the user can logon to.

1. Open up AD users and computers.
2. Right-click the username you need to restrict access
3. Select the Account Tab
4. Click "Log on to" button
5. Select "The following Computers" bullet
6. Type in the computernames you want the user to be able to log on to. Don't include the ones you don't want him to beable to log on to

Hope that helps



You can FORCE them to use their UPN login name, and remove the drop down box completely:

To remove the domain drop-down list from the logon screen and force users to use their full user principal name (UPN), perform these steps:

Start the registry editor (regedit.exe).
Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon registry subkey.
From the Edit menu, select New, DWORD value.
Enter a name of NoDomainUI and press Enter.
Double-click the new value and set it to 1. Click OK.
Reboot the machine.
The logon screen will no longer show a drop-down list for domains, and users will need to enter the full UPN to log on. For example, the user of an account called John in domain savilltech.com will enter the logon name john@savilltech.com.

One word of caution on this:

1.  The user has to use their UPN, not their pre-windows 2000 login (so if your UPN is john.smith but your pre2k login is jsmith, they won't be able to use jsmith anymore) and they'll have to include the @domain.com part too.
