Hello! I have a problem with ADCR and can't solve it alone.


I installed Netwrix AD Auditor, configured domain admin Account for AD auditing, install SQL Server, Created ReportServer and Netwrix_Auditor_Active_Directory databases, configured long-term archive. Configured schedule and finally got my daily report after initial log collection in my domain. All worked fine couple of weeks, after that Netwrix stops to send reports. I tryed to find a problem with Email send, but in netwrix auditor AD reporter there was no data, and Netwrix_Auditor_Active_Directory had no audit data too.

I start to dig deeper and find C:\Program Files (x86)\Netwrix Auditor\Active Directory Auditing\Tracing\ADCR-domainName.txt file.

File starts with lines like "ADCR.exe Information: 0 :" but next, file have some error:


"ADCR.exe Error: 0 : [TID: 1, Time: 15.01.2018 10:49:44] Unable to obtain previous value for change e5add9b8-9583-470d-a0ca-64dc596e53ca. The error is: System.IndexOutOfRangeException: Index was outside the bounds of the array.

There are a lot of this errors in tracing file. I have no idea what to do with it. :( :(




Thank you in Advance

P.S. Sorry for my English.

Hello Lea2312.


Could you kindly provide logs from the following location (the entire folder):

C:\Program Files (x86)\Netwrix Auditor\Active Directory Auditing\Tracing

Also, please gather “Netwrix Auditor System Health Log". To do that, please perform following steps:

1. Start "Event Viewer" on the machine where you have Netwrix Auditor installed
2. Expand "Applications and Services Logs" hub
3. Right-click "Netwrix Auditor System Health"
4. Select "Save All Events As..."

Either zip those files and attach them to your reply. Or use netwrix.com/upload form.
For latter, please specify topic name in the "Subject" field.

Best Regards,
