A while back I came across some software with which I could fully control a remote machine, but I can't remember its name. I now want to do some automation from my server so that I can put files on remote client machines, execute some commands, or get a list of processes on client machines.
I don't want to have any special software installed on my remote machine - I think there is a port by which I can do it. The only think I know about the client machines is the administrator account name and password.
Are there any built-in services in Windows that can be used to do this, and if so, which port does it use?
I'm aware of telnet but I don't think that's the software I had previously used.
