xp login password question

[screwd]

Thanks all and |3lack|ce for that example...

|3lack|ce, would the xp home/pro user have to have Remote Desktop, Terminal services, NetBios or any other services that opens a port running for someone to access the machine remotely like what you've described, say if Joe never had physical access to Freds machine to gather that information? Say I see no ports open when I do netstat, are there any hidden exploitable ports still open that simply don't/won't show up in netstat?

Also, |3lack|ce , could you further elaborate on those MS's backdoor accounts?

When I do net users command I only see Administrator, Guest, and a limited account I've set up.
