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.
