vista is like a four year old.
your not holding down the hard reset long enough. The lights will all go out, and I do believe all will flash once at the same time. You'll know when it happens ( I hope anyways).
you'll also want to make sure your own network settings in the adapter are reset. SOunds like you have it set to static, or somethign static. WIndows will say it's unidentified when it cannot find the gateway, which could indicate you had the gateway set to another specific IP address other than it's default 192.168.0.1.
