Symptoms

Consider the following scenario:

  • You have a DNS server that is running Windows Server 2008 or later versions.

  • The DNS server provides DNS services for the Internet telephony system.

  • The Internet telephony system uses the Name Authority Pointer (NAPTR) records to locate Session Initiation Protocol (SIP) services for telephones.

  • The DNS server compresses the DNS NAPTR records before the records are sent on the wire.

  • The telephony equipment or the other downstream clients decompress the NAPTR records.

In this scenario, the telephony equipment or the other downstream clients receive errors.

How to obtain this update or hotfix

To resolve this issue, we have released update rollup and a hotfix for Windows Server 2012 R2.

Before you install this hotfix, check the prerequisite of the hotfix.

The update rollup fixes many other issues in addition to the issue that the hotfix fixes. We recommend that you use the update rollup. The update rollup is larger than the hotfix. Therefore, the update rollup takes longer to download.

The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias.

However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8.1/Windows Server 2012 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
