KB2520155 and the Mysteriously Disappearing DNS Record

Our organization has an interesting bug with some of our servers – if they don’t “cleanly” shut down and are down for 15+ minutes, the DNS record is deleted when they come back up causing all sorts of issues.  The servers that were encountering this issue were all Windows 2008 R2.

While attending a recent local user group of IT professionals, Microsoft KB 2520155 (link here) happened to be mentioned during a presentation on a members journey of updating a SBS2003/Exchange 2003 server to Windows Server 2012 R2 and Exchange 2013.  As the article hasn’t been modified since 2012 who knows if the 2012 or 2012 R2 versions of Windows Server are prone to the issue or not.

What is interesting is we have had tickets open with Microsoft before regarding our issue and have had them check our systems with no mention of this particular article or the hotfix.

So if you have a randomly disappearing DNS record, whether client or server, check this out!
