Yes, the task scheduler. I think there's a new GUI around it in 2000, but I learned under NT 3.51, so I still use it via command-line.
Click on Start | Help, then search for "at command, using the at command" to get the online help for it. Note that you can also schedule jobs to run on remote computers.
You can be clever and surround several commands in a .cmd file, then schedule the command (batch) file to run.
