Deploying a protected wired network solution involves configuration of Active Directory, PKI, Group Policy, and RADIUS elements of a Windows-based authentication infrastructure. Once deployed, ongoing maintenance consists of managing 802.1X-capable switches and their configuration for changes in infrastructure servers and updating and deploying wired profiles. Common problems with wired connections include the inability to connect because of an authentication or authorization failure and the inability to reach intranet resources from the wired client.
