Vista - DHCP not starting Access Denied

I've been reading many threads about this issue, and I'm thinking I may need to do some scary registry edits.

I'm unable to connect to the internet. I recently turned of UAC. During a recent start-up, the scan disk ran, and 'fixed' a lot of corrupt and damaged files. After that, unable to connect to the net. I turned UAC back on, but still unable to connect.

I'm running Windows Vista Home Premium, so I don't secpol.msc, so I have to do the registry edits manually I suppose.

I'm at work so I don't have access to my home computer right yet, but I wanted to get this post up here now so people have a chance to read it over. If there is additional information you need, let me know.

Thanks.
