I recently went into my Action Center in Windows 7 to make sure everything was up to date, and I ran into one item - Network Access Protection (NAP), that is turned to Off.
When I click on "What is Network Access Protection" Windows says that it's "a platform that network administrators can use to help protect the security of a network. When you connect to a corporate network that uses NAP, your computer is checked to make sure that it has the required software and settings, and that the software and settings are up to date. If anything is missing or outdated, your computer can be automatically updated. Your network access might be limited during that time, but usually this process happens quickly, after which full network access is restored."
Sounds like it might be a good idea to turn it on. Of course, they don't provide a link to do so. Any insight from CWD forum people?
