SFW-HA installation prompts Driver Signing Warnings when Driver Signing has been set to Ignore on Windows 2003 x64

Problem

When running a silent installation script, or performing a manual installation of Storage Foundation for Windows with High Availability 5.1 SP2 onto a Windows 2003 x64 server, Driver Signing warnings still prompt for user input, even with Driver Signing in Windows System Settings > Hardware > Driver Signing has already been set to ignore.

This happens only with Windows 2003 x64 and SFW-HA 5.1

When installing SFW itself, or installing either SFW / SFW-HA on Windows 2008 or Windows 2003 x32, the issue does not take place.

Cause

The Operating System has two sets of Registry Keys for Driver Signing. Even with one disabled in Windows 2003 x64 (HKLM>Software>Microsoft>Driver Signing) there is a secondary key that can still leave Driver Signing Warnings set to enabled. This is by design, as per Microsoft's Knowledge Base article (http://support.microsoft.com/kb/298503).

Because of this, the GAB and LLT drivers (even though they are signed and even when running the SYMCCERT or Trusted Certificate option during installation) will still prompt a user warning.

Solution

To resolve this issue and allow for an unprompted installation, please perform the following steps:

- Verify there is not a Group Policy being pushed to the server which may overwrite settings

- Verify the user account operating the installation has Local Administrator priviliges, including installation of Signed / Unsigned Drivers

- Verify that under Control Panel > Settings> Hardware> Driver Signing, the option is set to Ignore

- Open the Registry Editor (Start > Run > Regedit)

- Browse to HKEY_LOCAL_MACHINE > Software > Microsoft 

- Highlight the Non Driver Signing key located here

- Change the value to be Zero (0)

- Restart installation and verify successful completion without Driver Signing Prompt.
