SQL Server 2000 + ASP.NET: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'
- by Rick
I just migrated a development workstation
FROM: Windows XP Pro SP3 with IIS 6
TO: Vista Enterprise 64bit with IIS 7
Since the move, one of my pages that accesses an SQL Server 2000 database is receiving the following error from my ASP.NET 2.0 web page: "Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'."
I have:
enabled Windows Authentication in IIS and web.config
disabled Anonymous Authentication in IIS
set up Impersonation to run as the authenticated user
verified that the logged in user (in this case, me) has access to the appropriate database on the SQL Server
verified that my login and impersonation information is correct in the ASP.NET page by checking User.Identity.Name and System.Security.Principal.WindowsIdentity.GetCurrent().Name (both display my username)
My connection string using SqlConnection is "Server={SERVER_NAME};Database={DB_NAME};Integrated Security=SSPI;Trusted_Connection=True;"
Why is it trying to login with NT AUTHORITY\ANONYMOUS LOGIN? I have to assume it's some setting or web.config entry specific to IIS7 since it worked fine before the migration.
NOTE: The SQL Server is Windows authentication only - no mixed mode or SQL only.
