SQL Authentication failure after applying windows 10 Computer Security Compliance GPO

(0) ShareShare

Posted on by Community Member

Hello,

I Have a issue connecting to SQL Server from NAV client.

We have 2 systems , System A SQL Server Express and System B NAV Client.

Both the systems are in AD and the SQL server service is running with NT Service account  and when we connect NAV Client with AD User from system B to System A everything works fine with no issues.

Once we apply the windows 10 Computer Security Compliance GPO ( https://blogs.technet.microsoft.com/secguide/2016/10/17/security-baseline-for-windows-10-v1607-anniversary-edition-and-windows-server-2016/)

NAV client from system B  with AD user  is not able to connect to the SQL Server but a domain admin account works fine.

Ports are working tested with telnet, no issues with firewall.

Also tried running the SQL server with a AD service account still has the same issue.

Please help in identifying the settings in the above GPO which is breaking the connection.

Thanks

Mo

    @manish: connector for crm (connector for dynamics) is the tool to integrate crm and nav (interchange sales quotes, ...). so it's ok to publish the question here.

    @mcyc: i suggest, you publish the question also in the crm forum.

    mcyc, you have tagged the issue as Connector for CRM and you are asking issue for NAV Client, Can you please clarify the issue is related to NAV client or Connector for CRM.
