The below example is from a Win 2000 server. You should be able to use kill "process name" and it should smoke everything in the tree. Similar to "pkill" in Solaris. I am not a Win admin so I am not sure if they don't have some extra command line kit like ptools installed here or what but you may want to check into it.....(updated) In windows 2003 you have to use: tskill "process ID"
process bpsched.exe (860) - '' killed
process bpsched.exe (852) - '' killed
process bpsched.exe (4168) - '' killed
