We have approximately 500 computers on a network. All are Dells running Windows XP Professional. The onboard NIC (Intel Pro/1000 MT Network Connection) is configured with a static IP address, and the Link Speed & Duplex setting is set to 100/Mbps/Full Duplex. On occasion, we discover that some of these computers have somehow changed over to DHCP, and the Link Speed & Duplex setting has changed to Auto Detect (which drastically reduces the performance of the computer). We have no idea what might be causing this change. Any ideas?
Thank you in advance!
