I forgot how easy it is to crash NT4 these days..
I had run this tiny WMI Script to enumerate the installed hotfixes on an old NT4 box.
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_QuickFixEngineering",,48)
For Each objItem in colItems
Wscript.Echo "HotFixID: " & objItem.HotFixID
Wscript.Echo "Name: " & objItem.Name
Wscript.Echo "Status: " & objItem.Status
Leave that running and before you know it, WinMgmt.exe will have consumed all available memory (virtual and otherwise) and the server is on its knees.
the reason being is that M$ changed their naming strategy in way hotfixes install themselves into the list of hotfixes applied. WMI_Quickfix engineering enters an endless loop trying to enumerate them.
M$ refused to fix this of course.. Why fix something when you just release a new version.
