Recently I worked on a case for a Fortune 500 company that was having problems to render the RSS Viewer Web Part in their SharePoint 2013 farm. They still have a SharePoint 2010 farm in the same network environment and this farm was not having problems rendering the RSS Viewer. The constraint was this:

There are several resources out there claiming SharePoint 2013 and 2010 are not compatible with TLS 1.2 but no official stance from Microsoft either way until now. This post is still not the official response, but it is the first step in this direction. Official documentation to follow. The official supportability is explained in the

  I have mentioned the steps to troubleshoot Claims to Windows NT Service (c2WTS) problems in a previous post (click here). There is also a post to see if the problem is with Active Directory (AD) or c2WTS (click here). After doinf the normal troubleshooting outlined in the previous posts you still have an issue

  I had previously discussed this topic here but it would not work for ULS tags with 5 digits (SharePoint 2013 and beyond). This post will guide you to create the rule for this particular ULS log entry: First, download DebugDiag 2 Update 2 or greater. As of the time of this writing it can

I mentioned it on another post how to identify the cause of an application pool recycle, but now

  This is a short one, I promise. A colleague was complaining that NetExt command !whttp was not displaying the active/finished requests on a dump file he was sure it was processing http requests. The truth is that the process was not w3wp.exe (IIS Worker Process) but rather a self-hosted WCF service. The command !whttp

  One of the problems that many C++ native developers face when interacting with .NET is the inability to load a .NET COM Dll and use the COM classes without registering the DLL. I faced this problem when adapting the debugging NetExt from pure C++ to pure C++/.NET. As the idea of an extension is

  Named pipes created by WCF does not look like the endpoint at all. I discuss this at length here: Named Pipes in WCF are named but not by you (and how to find the actual windows object name) I wrote an console application to test it and I detailed this here: Console Application to
