Remote Administration

Hi all,
I have a problem I would like to check with some knowledgable people.
I have 2 XP home computers on my home lan as well as another XP home
system running at a friends home. On my main system I run XP Pro and would
like to be able to administer all the home computers from my main one as
running up and down stairs as well as driving across town to get anything
done is annoying as hell. I have already set up an administration account
with the same user name/password on all machines and would like to know what
I should do from there.
Friend has asked me to administer hers since I built and installed all
her software as well as control who gets an account and such in the house.
She has asked if there was a way for me to be able to lockout accounts at
certain hours and if I would also be able to disconnect them if needed as
she knows nothing about computers other than basic user knowledge. Any help
would be greatly appreciated as I am at a lose on where and exactly what to
do. I know XP Pro has the remote desktop but did not see an option for it
in the home version so am lost.

TIA
