Installing CF 10 on Server 2003 ISAPI Errors

We have just recently went to try CF10 on Server 2003. I unistalled CF7MX and installed CF10, Server Configuration.

When I attempt to open the site for admin i get a 500 error. Looking at the logs, I see the following error: Could not load ISAPI filters for the site/service.

Anyone have any ideas what could be causing this.

I have run the wsconfig.exe and added the default site.

I also get this error:

The HTTP Filter DLL C:\ColdFusion10\config\wsconfig\2\isapi_redirect.dll failed to load. The data is the error.

THanks
