Hi everyone! You many help me, thanks a lot. I hope you kind to help me now. My NXLog clients don't collect Windows System logs. And now I often see in my logs this message: ``` 2019-06-04 17:49:50 INFO nxlog-4.3.4308 started 2019-06-04 17:49:50 ERROR failed to subscribe to msvistalog events using bookmark: The interface is unknown. 2019-06-04 17:49:50 ERROR failed to subscribe to msvistalog events using bookmark: The interface is unknown. * * 2019-06-04 17:49:50 ERROR failed to subscribe to msvistalog events [error code: 1717]; The interface is unknown. ``` My config: ``` define ROOT C:\nxlog define NXLOGLOGFILE %ROOT%\data\nxlog.log define CERTDIR %ROOT%\cert PersistLogqueue TRUE SyncLogqueue TRUE CacheFlushInterval 0 CacheSync TRUE Module im_msvistalog ReadFromLast TRUE * Exec $FileName = 'winapp.log'; Exec $EventTime = $EventReceivedTime; Module im_msvistalog ReadFromLast TRUE * Exec $FileName = 'winsys.log'; Exec $EventTime = $EventReceivedTime; BufferSize 9500000 Module om_batchcompress Host 192.168.100.100 Port 1514 UseSSL true AllowUntrusted TRUE CAFile %CERTDIR%\cacert.pem CertFile %CERTDIR%\clientcert.pem CertKeyFile %CERTDIR%\clientkey.pem Path winapp, winsys => out ``` After restart service nothing new. Any ideas, please!
