If you've been reading this blog over the last few months, you might have noticed a post that I did called: SCOM - Essential Community MPs, Scripts & Tools to Enhance Your Deployments. In this post I mentioned some excellent free tools developed originally by Microsoft's Boris Yanushpolsky that form a part of nearly every SCOM deployment I work on. I also mentioned that these tools received an overhaul by Microsoft's Daniele Muscetta to make them compatible with SCOM 2012.
News just in is that Daniele has given the MPViewer tool an update to resolve some bug issues and if you haven't used this tool yet, then I'd highly recommend downloading it along with the OverrideExplorer and Proxy Settings ones. They'll save you a heap of time in the long run with your SCOM troubleshooting and deployments.
