If I'm not wrong this update is dor windows 2000.I'm running XP.But anyway I download the update, I extracted and inside the folder update there is a file update.ver, I opened with notepad and sound like the update modify several files agentdp2.dll, agentdpv.dll, agentsvr.exe, sp3res.dll. When you run windows update probably only check the version of the files, so at this point I think that replacing the old files wiyh the newones should do it. In the other hand you can run the update with a command Windows2000-KB920213-x86-ENU.EXE /q /z. (What is quiet no rsetart) or ad any parameters that you want . Good Luck!
