Having Problems with service CCSVCHST.EXE not releasing memory when logging off. This has happen every since I updated to the new Norton 360. User Profile Hive Error. 1517. This is often caused by services running as a user account.. And in this case it is..Never had any Profile Hive Errors before the new update. This is happening on all of my Windows XP machines. .And is getting very irritating... and Yes I know I can download the user profile hive program but why should I ? 
Current System: WINDOWS XP PROFESSIONAL SERVICE PACK 2. 4gb Ram.
Thanks to anyone who can help.
