Windows 2000 killprocesses command scrip

I need to kill some unnecessary processes in Windows 2000 with help of a .BAT file.
This utility can be used in an automated script…
Which command can I use?
For instance in Windows XP is:
TASKKILL [/S system [/U username [/P [password]]]]
{ [/FI filter] [/PID processid | /IM imagename] } [/F] [/T]

Thank you!…
