It absolutely does. I found out the hard way after blue screening a customers production server. Sent the dump off to Microsoft and they came back with regsys.sys as being one of the causes. So after some research, and consulting the very knowledgable Rick Mack, I learnt a very valuable lesson. Rick said that "...regmon is quite capable of bluescreening a server if you're using it on a production system (users logged on) with no filtering to restrict the amount of info it's getting. If you limit input by specifying a particular executable, or better yet a particular PID, it's generally safe to run it. However if you want to monitor things globally, don't do it on a production server with lots of users logged on." I hope Rick doesn't mind me quoting him, but I can't explain it as well as he does. Cheers.

It's never caused an issue for me so maybe we are talking about different regmons. -----Original Message----- From: Stratton, Doug ISMC:EX [mailto:Doug.M.Stratton@xxxxxxxxx] Sent: 19 May 2006 00:44 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Profiles not unloading Thanks that was could be a big help. I will try it next time it happens. As an asside, has anyone out there had regmon blow up thier servers. Twice now I have used it and it has crashed our w2k3 servers. We are thinking about buying it but know I am thinking it won't work for us.
