Troubleshooting: Create DCOM Instance Error = 80070005, Unknown error. Created qbXMLRP2 OK.

Problem Description:

When trying to use SQL Server via QODBC, It reports the error like this:

Create DCOM Instance Error = 80070005, Unknown error. Created qbXMLRP2 OK.


Please open your Services list window(services. msc), Search for your SQL Server service, right-click the server you are using, and click the "Property" option to view the server information.

In the "Log On" window, please check that you have set your server like ( NT Services\MSSQLSERVER ):

We believe that this is the reason for your problem. Please change your Server User like the screenshot below: (empty the password and confirm the password if using "Network Service" or Consult with your System/Network Administrator)

If that does not work for you, try using "Local System User":

Ah, hmm. Yes, setting the SQL service account to SYSTEM or an account with membership in Administrators local group gets this DCOM component working for me. Cannot use a non-privileged account for the SQL service apparently. Not ideal from a security point of view.

Hi Paul,

You can use QRemote, QRemote doesn't require any account/security change for use SQL Server. Please refer:
