Exchange & Outlook UPDATE
MS13-061 Causes Search Controller Headaches for Exchange 2013
AUT_TonyRedmond_70x91
by Tony Redmond
Microsoft issued a set of security fixes, including a critical patch (MS13-061) that affected Exchange 2013, Exchange 2010, and Exchange 2007. The Exchange product group duly released roll-up updates for Exchange 2007 SP3 (RU11), Exchange 2010 SP2 (RU7) and Exchange 2010 SP3 (RU2). All was well for Exchange 2013 RTM CU2 because the new servicing model is designed to allow security patches to be applied to a server without requiring Exchange to be updated. All was well in the world. Until, of course, a bug appeared.
 
Update 9:41AM (Pacific) 14 August: Microsoft has temporarily removed MS13-061 to fix the problem reported here. If you already have the update, you can install it and fix the problem afterwards as described below.

In Microsoft Office Communications Server (OCS) 2007 R2 and earlier, the only supported load balancing solution is a hardware load balancer. Fortunately, Microsoft introduced DNS load balancing in Lync Server 2010.
DNS load balancing in Lync Server 2013 hasn't changed much from that in Lync Server 2010. I'll answer three questions commonly asked about the Lync DNS load balancing solution found in these two versions.

Exchange 2013 Diagnostic and Performance Log Files
AUT_TonyRedmond_70x91
by Tony Redmond
A recent question in the Exchange TechNet Forum asked about Performance Monitor (PerfMon) data collector sets that appear in the \Microsoft\Exchange Server \V15\Logging\Diagnostics\DailyPerformanceLogs folder, where you'll find files named ExchangeDiagnosticsDailyPerformanceLog_MMDDHHMM.blg. Another folder (\Microsoft\Exchange Server\V15\Logging\Diagnostics\PerformanceLogsToBeProcessed) holds a slightly different PerfMon data collector set, the content of which is gathered and then merged into the daily performance log on a regular basis by the Microsoft Exchange Diagnostics service. The question expressed a concern that Exchange generates these files automatically and takes up disk space for no obvious reason. In fact, the files are used by Exchange's Managed Availability framework (which runs as the Microsoft Exchange Health Management service) to track the health of system components, so they serve a useful purpose.
