Hello everyone, I'm having a problem here with RIPREP images. I've sucessufully made an RIPREP image, published on a RIS server. Now the problem is to download the image from the RIS server. When I start the process I get a message saying that I don't have the necessary network drivers to continue. Where should I put the network drivers? I've read a lot of articles describing where to put them, but that just don't seem to work 'cause when I stop and start the RIS service it doesn't create any *.PNF files. Any1 can help?
