There are a large number of SQL Server Native Clients in the "System Management Events" of the SQL Server server 11.0 mistake，I originally thought it was a problem of SQL operation level, and I ignored it.，Then one day I checked online，Only to find that it is related to ESET。
SQL Server Native Client 11.0: Unable to load sqlnclir11.rll due to either missing file or version mismatch. The application cannot continue.
From This ESET's official discussion thread，It seems to be SQL Server 2014 There is a problem with the certificate of the version sqlnclir11.rll file，So ESET believes that Microsoft will handle this problem，But Microsoft ignored it，So this problem has always existed。Fortunately, in the end, ESET officials still provide a way to adjust ESET settings，To avoid this problem。
【step】
◎ Enter ESET "Advanced Settings" screen，Find the order and click "Detect Engine"-"Auto Exclude"-"Auto Exclude"，Just cancel the "Microsoft SQL Server" item。
This problem seems to occur only in SQL Server 2014，ESET official said 2016 No such problem。
