I tried the udated atapi.sys file, but it didn't work. I started getting the same message about other files. Every time I tried to install win2k server it would hang on a different file. I decided to get crazy, I decided to try the brute force method, I tried installing it 27 times in a row, and I finally got through on the 27th time. This is not something you'd find in an MCSE handbook, but it seemed to get the job done this time. Thanks for your insight
