DontDisplayLastUserName Setting Lost Upgrading from Windows NT 4.0 to Windows 2000

• Microsoft Windows 2000 Advanced Server
• Microsoft Windows 2000 Datacenter Server
• Microsoft Windows 2000 Server

SYMPTOMS

When you upgrade from Windows NT Server version 4.0 to Windows 2000 Server, the Winlogon DontDisplayLastUserName value is overwritten from a value of 1 to 0. The following registry entry is not maintained:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

Value: DontDisplayLastUserName
Type: REG_SZ
Default: 0 : Displays last user name
Other: 1 : Does not display last user name

CAUSE

When you upgrade to Windows 2000 Server with Terminal Server Services selected, the Terminal Server .inf file (Tsoc.inf) changes the value to 0. This value is not changed if Terminal Server Services are not selected during the upgrade.

RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To work around this problem, edit the registry value listed above to reflect the appropriate functionality, or use the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System\DontDisplayLastUserName
