JSI Tip 10515. You receive 'Error code: -2147467259 (Unspecified error)' when you attempt to install Microsoft Operations Manager 2005 Reporting?

When you attempt to install MOM 2005 Reporting on a Windows Server 2003 SP1 (Service Pack 1) computer, you receive:

Failed to create data source for Data Warehouse. An exception occurred. Check that you can access the SQL Services Reporting Server from this machine. Error code: -2147467259 (Unspecified error)

This behavior is the result of a new SP1 security enhancement, a loopback check security feature, designed to help prevent reflection attacks.

To workaround this behavior, you must disable the loopback check security feature:

1. Open a CMD.EXE prompt.

2. Type the following command and press Enter:

REG ADD HKLMSYSTEMCurrentControlSetControlLsa /V DisableLoopbackCheck /T REG_DWORD /F /d 1

3. Shutdown and restart Windows Server 2003.

4. Install MOM 2005 Reporting.
