thread.currentprincipal.identity.name & pre windows 2000 domain na

[=?Utf-8?B?RHVuZTg4?=]

Hi there,

We're using windows authentication in our web app and calling
"thread.current principal.ident ity.name" to get the currently logged on user
name. On our system, the "pre-Windows 2000" field is set for domain users in
Active Directory and "thread.current principal.ident ity.name" returns:

pre-Windows_2000_do main\username

Is there any way to get the fully qualified domain name from the
currentprincipa l?

Cheers
