Most likely causes:
  • The username supplied to IIS is invalid.
  • The password supplied to IIS was not typed correctly.
  • Incorrect credentials were cached by the browser.
  • IIS could not verify the identity of the username and password provided.
  • The resource is configured for Anonymous authentication, but the configured anonymous account either has an invalid password or was disabled.
  • The server is configured to deny login privileges to the authenticating user or the group in which the user is a member.
  • Invalid Kerberos configuration may be the cause if all of the following are true:
    • Integrated authentication was used.
    • the application pool identity is a custom account.
    • the server is a member of a domain.
Things you can try:
  • Verify that the username and password are correct, and are not cached by the browser.
  • Use a different username and password.
  • If you are using a custom anonymous account, verify that the password has not expired.
  • Verify that the authenticating user or the user's group, has not been denied login access to the server.
  • Verify that the account was not locked out due to numerous failed login attempts.
  • If you are using authentication and the server is a member of a domain, verify that you have configured the application pool identity using the utility SETSPN.exe, or changed the configuration so that NTLM is the favored authentication type.
