SYMPTOMS
========

When you install Exchange Server 5.5 on a server that is running either
Microsoft Windows 2000 or Microsoft Windows NT 4.0, you may receive the
following error message:

  You must be logged in to a Windows NT Domain to run Microsoft Exchange Server
  Setup.

CAUSE
=====

This issue can occur if the automatic administrative logon functionality is
enabled. This functionality is enabled if the following if the registry value is
set to 1:

  NT\CurrentVersion\Winlogon\AutoAdminLogon

Some programs enable this functionality by default to facilitate long or
complicated installation routines. You can also enable this functionality
