- Make sure that your MOSS server is part of the domain whose users you are trying to authenticate against your portal. If it is and you still get error then remove your MOSS server from your domain and delete the server name in the domain, then add the server into domain again
- Check the DNS configuration (Under TCP/IP settings) of your web server and see that it points to your AD DNS (probably your AD server) and not to the ISP DNS (Make sure you are aware of any Firewalls or Filters between your AD server and MOSS server)
- Also make sure that your certificate authority (CA) is also your domain controller, you're going to need to find out what IIS is giving out for a cert and then make sure there are no bad DNS entries in there for that.
- If above doesnt work, try IE Tools > Settings > User Authentication settings for the Local Intranet zone, check “Automatic logon only in the Intranet zone” is selected. If selected then try resetting to User Authentication to “Prompt for user name and password” and the issue might be resolved.
