The Division of Information Technology has implemented the CAT tool to better protect students from viruses and threats on the internet. CAT will check your computer to ensure that your computer is up to date with:

1. All of the released Microsoft Critical Patches, and
2. An AntiVirus program with updated definition files.

You must pass CAT in order to register your computer on ResNet. Clicking on the link at the bottom of this page will initiate CAT. It may take some time for the tool to load, please be patient.

The CAT tool will only run on Windows machines (Win 95/98/ME/2K/XP). Therefore, all MAC and Linux users should go directly to the registration page. If you are a MAC or Linux user who is seeing the CAT page and asking you to check your computer, please contact Client Support at 2-9800.
