Problem With Login null

Hi,
I have a problem. My web server is a Windows 2k Server and my database
server a Windows 2003. I use windows authentication to login at SQL Server,
but when I access from a client machine that uses Win 2k Professional I
always receive this message: "[Microsoft][ODBC SQL Server Driver]
1;SQL
Server]Login failed for user '(null)'. Reason: Not associated with a trusted
SQL Server connection.".
When I access from a client machine that uses Windows XP everything its
ok.
This problem only occurs at the web site. When I try to access the Query
Analyzer or the Enterprise Manager I still have the connection.
Can anyone help me?!
Thanks,

If your web application is attempting to use the credentials of the web
client, then you'll need to implement
Security Delegation to get this to work.
Here's a good whitepaper on setting up Kerberos Delegation.
