PRB: Error 80070005 "Unexpected Error" When You Use Remote Data Service

When you use the RDS.DataControl object to return data by using Remote Data Service (RDS), you may receive the following error message:

RDS relies on the following registry keys: This error can occur when these registry keys either do not exist or their permissions are too restrictive.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve the error, perform the following steps:

1. To determine if the above keys exist, use Regedit.exe or Regedt32.exe. If the keys do not exist, add them.
2. To determine if the key permissions are too restrictive, open Regedt32.exe, and select the registry key. On the Security menu, click Permissions to view the Access Control List for the key. The authenticating user must have at least Read permission to the registry keys.
   
   NOTE: The user account is determined by the authentication method settings of the MSADC virtual folder for the Web site. If you are using anonymous access, the user account is the IUSR_computername account.
3. Restart your Web service.

Error 0x80070005 can also occur if the Business Object component is not added to the ADCLaunch registry key. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
