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 HKLM\SYSTEM\CurrentControlSet\Control\Lsa /V DisableLoopbackCheck /T REG_DWORD /F /d 1
3. Shutdown and restart Windows Server 2003.
4. Install MOM 2005 Reporting.
