You don't need to buy software. Indeed, any software like copilot that doesn't need anything installed on the remote computer is obviously using the services already available in Windows. It is probably just a different viewer.
Windows Netmeeting. This is good because it allows the user to see what you are doing. You can set it for low bandwidth but then it misses some video rewrites that make it a bit clumsy sometimes. No clipboard sharing. The remote computer needs to enable desktop sharing. Encrypted comms if enabled in setup. You can setup Netmeeting by typing "conf " in the Run window.
Remote Desktop Connection works better but the remote computer is locked while you are logged in. Clipboard and your drives can be shared onto the remote computer. Encrypted by design.
It is actually Microsoft Terminal Services originally provided for terminals running from Windows Servers. I think the remote computer needs XP Pro but Windows 9x can connect. Type mstsc in the run window of the client.
The free program, Real VNC (search this name) works well and allows both users to operate simultaneously. You can use it on Windows98. It even allows multiple clients to participate. You have to load the host service on the remote computer.
However VNC is not encrypted in its free implementation.
