If you have downloaded the latest update WMI or Norton Windows Mangement Instrumentation for NAV2004 it would pay you to go to the symantec support and read up about this little item before you instal SP2. Or if you have installed SP2 and run NAV 2004 you may have already had a security alert from symantec.
Go To http://service.symantec.com/SUPPORT/sharedtech.nfs/pfdocs/2004070812114713
Better still go to the site before you download SP2
