Error on 64 bit system

I have a new server that wont let me run the app I bought it for.  It is a multi processor Opteron 64 bit system running w2k3 enterprise 64 bit.  The main consistent error I get is this one and I cant really get any where googleing and trouble shooting it.  This is the error.

\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.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

I dont know what else to do.

It's telling you that npf.sys is not a 64 bit driver and WILL NOT work.

There are certain files that are not going to work on a 64 bit system(32 bit print drivers for one).

So you need to find a 64 bit npf.sys,if not ,it's not gonna work.

You trying to run WireShark?

so i just copy a 64 bit npf.sys into that directory?  any ideas where I can find those drivers?  There are probably more.. I thought that the wow64 was for running 32 bit apps on a 64 bit system
