The XP schtasks.exe command-line tool is great for managing scheduled tasks. Win2K doesn't have an equivalent command-line tool. If you attempt to run schtasks.exe on a Win2K machine, you'll receive an error message indicating that you're using the incorrect OS version. You can modify schtasks.exe to work under Win2K by performing the following steps.
- Open schtasks.exe in a hexadecimal editor such as BreakPoint Software's Hex Workshop 3.1.
- Find code location CB2A, and change the hex value 75 to EB. If you're using Windows XP Service Pack 1 (SP1), the code location is 0x0000CC50 (not CB2A); if you're using XP SP2, the location is 0x0000E3F8. Updated 12-5-08: If you're using XP SP3, the location is 0x0000E391.
- Save the file and exit the editor.
For cosmetic purposes, you can use Visual C++ or a resource editor such as Angus Johnson's Resource Hacker to change the error message
ERROR: The Target system must be running Windows XP or above.
to
ERROR: The Target system must be running Windows 2000 or above.
This error message is located in String Table 344.
