One Vista PC in our small office fails to initialize networking about 1 reboot in 3. Vista's diagnostics are never able to repair the issue. However, the problem can be consistently resolved (until the next reboot) by disabling and then enabling the network adapter in Device Manager.
This is a wired connection to a router. The network adapter is the onboard NVIDIA nForce 10/100 Mbps Ethernet with the current drivers available from Windows Update, and is the only network adapter in the system.
Has anyone seen this issue and hopefully know how to resolve it?
