Windows RIS updates

I had created a build set 3 years ago that included all the network drivers at that time in Windows2000. Over time, network cards update and the drivers are not found. We have had to change network cards to get the build set to work. Has anyone had success with adding new network card drivers to a RIS Build? I had gone through an older article from Microsoft, but the new driver is not being recognized. Thanks for any help on how to do this.

Thanks
