We have a customer with a HP Compaq 6710b notebook (on a docking station) running XP SP3. Also running Symantec Endpoint Protection. Client's machine is not on a domain. Client has recently complained of the system locking up on startup. He has waited for over an hour in some cases, then system will act normally. We have determined that if the user does nothing more than hit the cntl-alt-del key combination the system will return to normal. Do not even have to kill any process, just hit cntl-alt-del. This occurs in safe mode as well.
