Killing Processes in Windows 2000

I have trouble in Windows 2000 with certain programs and processes that stay around even when the application is frozen. (The two applications that I consistently have problems with are Adobe Acrobat Reader and Microsoft Outlook.) I've tried numerous ways to get rid of the application, but I can't find anything that seems to match the UNIX kill command. Do you have any suggestions?

I like ptreeg.exe, which is the GUI client for the Process Tree (ptree.exe) utility in the Windows 2000 Resource Kits. This tool will show you all processes that are running on a computer and let you kill any of those processes. The application is particularly easy to use, lets you monitor more than one computer, and even lets you kill processes remotely.
