SYMPTOMS
When you migrate user accounts from Windows NT 4.0 to Windows 2000, the Properties of those accounts may display an empty User Logon Name text box when you view them in the Active Directory Users and Computers MMC snap-in. This is also true for all Windows user logon (SAM) names that comply with any RFC-compliant version of Domain Name System.



STATUS
Microsoft has confirmed that this behavior occurs by design.



MORE INFORMATION
Although the User Logon Name value is not automatically populated, an implicit Universal Principal Name (as defined by the IETF RFC 822 in the form of @Fqdn.com) is assigned to every account by default. This takes the form of the user's SAM account combined with the fully qualified domain name. For example, @Fqdn.com.
