Several desktops are reporting a message: low disk space. After investigating, most of these systems are showing under 500 mb remaining free space. The windows folder on most systems show a size of 64 gbs. One is 50 gb. these systems are 75 gb drives. The users are not administrators therefore no unnecessary applications are loaded. Searching the systems I see no file with an excessive size. VirusScan is up-to-date. All systems are Dell factory images and have the same applications loaded, ie office2003 suite, mcfee virusScan. The system restore is set to the max of 12% - a little over 9 gbs.
