Why are my AT and SOON commands not working properly?

A. When you install IE5 on NT, IE replaces the Scheduler service with its own "Task Scheduler:; this messes with the AT and SOON commands (for example, see http://support.microsoft.com/support/kb/articles/Q237/8/40.ASP http://support.microsoft.com/support/kb/articles/Q214/4/20.ASP and other KB articles). Microsoft's documentation on this (and especially how to remove it) is confusing and contradictory. The only article that explains how to revert to the Scheduler service in a way that worked on my machine is: http://support.microsoft.com/support/kb/articles/Q226/3/70.ASP but note that if mstask.inf does not exist you can specify mstask.pnf and the "uninstall" will work. The basics are described below:

Internet Explorer 4.x

To uninstall the Internet Explorer 4.x Task Scheduler:
  1. Click Start, point to Settings, click Control Panel, and then double-click Add/Remove Programs.
  2. Click the Install/Uninstall tab, click Task Scheduler 1.0 (Remove Only).
  3. Click Add/Remove, and then click Yes when you are prompted to remove Task Scheduler.
  4. Click Yes when you are prompted to restart your computer.

Internet Explorer 5

To uninstall the Internet Explorer 5 Task Scheduler:
  1. Click Start, and then click Run.
  2. In the Open box, type the following command and then press ENTER
    RunDll32 advpack.dll,LaunchINFSectionEx %systemroot%\INF\mstask.inf,,,256
  3. Restart your computer.
