Windows 2003 R2 64 bit network auto discovery fails

Windows 2003 R2 64 bit network auto discovery fails

"The Netgroup Packet Filter service failed to start due to the following error:
This driver has been blocked from loading"

"\SystemRoot\SysWow64\drivers\npf.sys has been blocked from loading due to incompatibility with this system.
Please contact your software vendor for a compatible version of the driver."

Heres the event logs. Looked through KB, manuals, not luck. New to 64bit so maybe I need to tell it to use 32bit for sys file.
