DCDiag take a long time to run on Windows Server 2008 R2 and Windows 7

Posted by John Policelli on March 9th, 2010

DCDiag.exe is an extremely useful built-in troubleshooting tool. I stumbled across a KB from Microsoft that explains that in certain environments, and under certain conditions, DCDiag.exe may take an excessive amount of time to run on computers with Windows Server 2008 R2 or Windows 7 installed. The good news is that MS has released an updated version of DCDiag.exe which fixes this issue. The KB and download can be found here: http://support.microsoft.com/?kbid=979294.
