Hi, I am a novice when it comes to Vista. I purchased a floor model Sony Vaio from Staples. I am logged in Vista as the Administrator but I still have no access to any changes as far as networking goes. I keep getting the message that "this resource is currently in use" and I can't change ANY settings. Can anyone shed some light for me on what I need to do to get Vista security toned down a notch so I can set up my home network? Thanks in advance!!
