Re: enabling admin$
I don't know if there is a function or command. On the computer i am on right now WinXP administrative priveleges, i can enable this share two ways:
1. Go to C:\Windows and right click. Click properties and go to the Sharing tab. Click share this folder. Share Name = ADMIN$
2. Go to Control Panel->System->Remote and click allow remote connections.
I am not too sure about the second one, I think the first time you do it, it will create the share, but the first one will work.
As the sun sets, the earth shall prepare
