Another one for integrated authentication

Hi,

When - on our Windows 2003 Terminal Servers - I try to open my
intranetsite for which Integrated Authentication is configured, I'm
asked for my credentials. The username is already filled in as
"hostname.domainname.local\username" which ofcourse doesn't exist. If I
change this to "domainname\username" en supply my password, all is OK.

IE is configured to use Intergrated Authentication, the enty
*.domainname.local is added to IE's Intranet Zone and I also performed
the "cscript adsutil.vbs set w3svc/NTAuthenticationProviders "NTLM"
command.

Why does IE or IIS (6.0) prompt me for my credentials using a local
user account (local to the web server) and not using my domain account?
