Question : Can you configure integrated/ntlm authentication in the Remote Desktop Client?

We have some applications that we have decided are going to be best served on a terminal server for internal users.  The Terminal Server is a Domain Member, and all users that will access it will be on Domain Member Workstations, logged on with thier individual valid Active Directory username/passwords.  I don't want the users to have to re-enter their username and password to connect to the terminal server.  Is there a way to enable integrated (using the IIS language I know here) authentication in a remote desktop connection?

P.S. I'm not interested in the 'save username/password' feature of the Remote Desktop Client.  We change passwords every 90 day's, and this 'work-around' will get inconvenient real quick.

If TS is running Windows Server 2008, you have the possibility to use single sign-on through CredSSP for clients running Vista/2008. The CredSSP is also supported in XP when upgrading to SP3.
With Windows Server 2003 TS, the answer is no.
