  • You try to create or run a linked server query.
  • The linked server query is created or run under the context of a user who is not a local administrator.
In this scenario, you may receive an error message that resembles the following:
Cannot create an instance of OLE DB provider "provider_name" for linked server "linked_server_name"

MORE INFORMATION

In Windows Vista and later versions, the TrustedInstaller system account owns the MSDAINITIALIZE DCOM class. The TrustedInstaller system account is the only account that has write permissions on the MSDAINITIALIZE class. Therefore, in Windows Vista and later versions, you must perform steps 1 through 6 in the "Resolution" section before you edit the properties of the MSDAINITIALIZE class.
