Connecting To MSDE Using SSPI

Please advise: I have created a simple ASPX page to test if I can connect to MSDE on a Server 2003 system. The connection string that works ok is:





server=WS1;database=northwind;integrated security=false;user id=sa;password=xxx;





but the string that does not work is:





server=WS1;database=northwind;integrated security=SSPI;





which is the string I would like to use for normal web access. This string works fine on my development system (where I use XP Pro and IIS 5.1)





In IIS6 on the "production server" the directory security on the virtual dir is set to allow anonymous access, using user IUSR_WS1 (where WS1 is the name of the system) and to integrated security.





Please help! Thank you
