Mostly computer was denied access because "The request was rejected by a third-party extension DLL file".To troubleshoot this problem efficiently, I suggest that you refer to the user manual of IDM to ensure that it is installed and configured properly.Meanwhile, I suggest that you contact the HP's support at the same time.Please understand that I don't mean to bounce you between support professionals as I am fully aware how time consuming this can be. However,they really are in a better position to be able to assist you with this issue as they may have experienced similar issues.In addition, for client authentication you can manually enroll a computer certificate to have a try.

Computer authentication only. When a user logs on, it has no effect on the connection. Only computer authentication is performed. The exception to this behavior is when a user successfully logs on, and then roams between wireless APs. In that case, user authentication is performed. For changes to this setting to take effect, restart the Wireless Zero Configuration service for Windows XP
