While changing service account to a new domain user by SQL Server Configuration Manager in a clustered SQL Server instance, “the server threw exception 0x80010105” may arise. This error comes from Windows side, since the new account can not reach out to the resource of cluster by making COM calls.

To give this right:

Login with administrative privileges to SQL Cluster nodes.

Click Start, type mmc in the Search programs and files box, and then press ENTER.

On the File menu, click Add/Remove Snap-in.

Under Available snap-ins, double-click WMI Controls, and then:

  • Select the computer that you manage. Connect to: select Local Computer, click Finish. Click OK.
  • On Console Root tree, select WMI Controls, right click, select Properties, then go to Security tab, locate root\Microsoft\SqlServer\ ComputerManagement10 (or 11 for SQL Server 2012) namespace then click Security.
  • Add new domain user to Group or Users Names
