Our company has recently went to Least User Privileges (users are not in local Admin group of their computer). When a user logs in they get an error message that "The feature you are trying to use is on a network resource that is unavailable". The file it is trying to find is MFEAgent.msi which is in the c:\Docs and Settings\All Users\App Data\Mcafee\Common Framework folder. After giving the users group execute permissions to this folder this error message will go away. The odd thing is every so often (may be after mcafee updates) some of the computers will have this error message reoccur and when the permissions on the folder is checked they have been removed. What would cause this?
