First of all, I won't be able to dig into this any more until next week - sorry about that. But others are always free to :-) There is no strace equivalent builtin, but you can get an addon from http://www.bindview.com/Services/RAZOR/Utilities/Windows/strace_readme.c fm. Don't put it on a production box permanently, though, it tends to cause BSODs in some cases. //Magnus ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
