When verification is complete, click Yes when asked if you wish to install the Hotfix for Windows (KB2956577). These requirements include some prerequisite updates. The Windows Update Standalone Installer will verify that the computer meets requirements to install the update. In the location where files were unzipped, double-click the Windows Update file, for example Windows8.1-KB2956577-v2-圆4.msu. Click Yes and confirm that All files were successfully unzipped is displayed, then click Ok. If the directory does not yet exist, you will be asked if you wish to create it. Type a location where you want to save the extracted files, for example C:\hotfix. In the Microsoft Self-Extractor dialog box, click Continue. ĭouble-click the self-extracting file, for example 475151_intl_圆4_zip.exe. If the DNS server is running Windows Server 2012 R2, download the hotfix from. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups ( ). ![]() Membership in the Administrators group, or equivalent, is the minimum required to complete these procedures. If the DNS server is running Windows Server 2016 Technical Preview or later, diagnostic logging is already installed and you can skip the first procedure, performing only the steps in To enable DNS diagnostic logging below. To install DNS diagnostic logging, the computer must be running the DNS Server role service. ![]() Perform the following procedures to install and enable DNS diagnostic logging on Windows Server 2012 R2. Installing and enabling DNS diagnostic logging However, it is always advisable to monitor DNS server performance whenever additional logging is enabled. There is no apparent performance impact for query rates of 50,000 QPS and lower. For example, a DNS server running on modern hardware that is receiving 100,000 queries per second (QPS) can experience a performance degradation of 5% when analytic logs are enabled. DNS analytical logs are not enabled by default, and typically will only affect DNS server performance at very high DNS query rates. DNS audit logs are enabled by default, and do not significantly affect DNS server performance. Audit and analytic event loggingĮnhanced DNS logging and diagnostics in Windows Server 2012 R2 and later includes DNS Audit events and DNS Analytic events. Debug logging can affect overall server performance and also consumes disk space, therefore it is recommended to enable debug logging only temporarily when detailed DNS transaction information is needed. The DNS debug log provides extremely detailed data about all DNS information that is sent and received by the DNS server, similar to the data that can be gathered using packet capture tools such as network monitor. See Using server debugging logging options for more information about DNS debug logging. Debug logging is discussed here because it is also a tool that is available for DNS logging and diagnostics. DNS debug logging is not the same as the enhanced DNS logging and diagnostics feature discussed in this topic. Prior to the introduction of DNS analytic logs, DNS debug logging was an available method to monitor DNS transactions. The following sections discuss DNS server performance considerations when additional logging is enabled. Using DNS server audit and analytic eventsĭNS server performance can be affected when additional logging is enabled, however the enhanced DNS logging and diagnostics feature in Windows Server 2012 R2 and Windows Server 2016 Technical Preview is designed to have a very low impact on performance. See the following sections in this topic: This feature is also available in Windows Server® 2012 R2 when you install the query logging and change auditing hotfix, available from. Enhanced DNS logging and diagnostics is available by default in Windows Server® 2016 Technical Preview.
