Windows 2000 Error: A domain controller for your domain could not be contacted


By default, Windows 2000 suppresses error messages when logging on a user with
cached credentials when the domain controller can not be contacted. A common
situation when a laptop user is traveling.

In Windows NT 4, the default is to display the error message. There are
security implications. See Cached
Logon Hashes
for details on this and related registry keys.

If you want to display a message that the domain controller is unavailable,
you need to set both ReportDC=1 which is an NT/W2K/XP
setting and ReportControllerMissing=TRUE which is a
W2K/XP setting.

Key:
Software\Microsoft\WindowsNT\CurrentVersion\Winlogon

NT\CurrentVersion\Winlogon
