I have a Dell D820 mobile computer. For some reason if the computer is turned off the wireless zero conf service will not be started the next time the laptop is powered on. Each time I have to go into services and restart the wzc service. In properties it's set for automatic and the laptop is not using a dell proprietary wireless service that I know of. How can I set this laptop to always keep this service on or what do I need to look for that may be causing this issue?
