I just acquired a new small business client with a Windows 2003 server and 8 XP / Windows 7 clients. The server is running DNS.
This morning while troubleshooting some DNS 4004 & 4015 errors in the Events Viewer, I noticed that on the NIC Authentication tab, "Enable IEEE 802.1x…" and "Authenticate as computer…" are selected. Other 2003 DNS servers I maintain for other networks do not have these features enabled, including one I myself setup using the Server Roles wizard. Should these settings be left enabled, or turned off. What is there purpose? I am in the process of getting familiar with this network. This server holds some data and hosts a business application, nothing unusual. Thanks for the advice.
