Process Monitor (or procmon) is a very powerful diagnostics tool for Windows. I remember when I first run it, a few years ago, I was overwhelmed by the number of events happening on my system each and every second. Thankfully, procmon has features to help you deal with this bulk of data, including filters, highlighters, and bookmarks. But sometimes even a filtered log is not enough to find the root cause of a problem. On such occasions, other log sources may contain the missing bits of information. We only need to correlate them with our procmon trace. And today, I would like to show you how I do that.
In this short post I would like to show you how, with sysinternals tools, you may noninvasively trace .NET applications. This is especially useful in production environment where you can’t install your favorite debugger and hang whole IIS to diagnose an issue. We will work with three tools: dbgview, procdump and procmon. Let’s start with the first one.
After Microsoft has rolled out a stable version of Windows 8.1 I wanted to have it installed on all my computers. The update went smoothly on my home desktop and a tablet but I had problems on a PC at work – the Store application could not connect to the Internet and I kept getting an error message: We weren’t able to connect to the Store. This might have happened because of a server problem or the network connection timed out. Please wait a few minutes and try again.. I was not able to find a solution on Google so I started my own investigation.
