windows 2000 RIS……

I have installed the RIS component to my 2000 server. I have created a couple of images….works great. I create the remote boot floppy….it works great…it begins to load the Windows 2000 files and at the point of formatting and partitioning the drive it gives me an error saying it cannot complete the task because of either a lack of memory or corrupt windows 2000 files. I have tried it with a couple of different locations, with still no luck…Any ideas?
