anyways....
download tightvnc
Install it as a service and set up the password.
Then go into the registry and delete the key in computer>software>microsoft>windows>current version>run> will be something like "tightvnc.exe -servicehelper"
That will disable the icon in the task bar, so he wont know its installed. Then just reboot, or kill the icon in the tak bar and manually restart it.....if you dont know how to restart a service, it's best to just reboot
after that, install tightvnc on your machine, and log into his, you can set it so you view only, or you can set it so you take control completely of his computer.
I use that all the time to work on my home computer from work, and work from at home. It's also cool if you want to keep an eye on employees or whatever, because if you click the "view only[inputs ignored]" option on the client before you connect, they wont know you're watching at all.
It's even somewhat reliable over a 56k connection if you set custom compression level to 9, and jpeg compression to 0, and turn them both on.
