I was doing that from memory, so I might have done something wrong. However, right now I have my copy open here, and you have to do the following:

1: Make sure you have a file called Network Access.image.

2: Open up the Floppy Image program.

3: Under Write Floppy, click Browse.

4: Locate the image file and click "Open"

5: Click "Start"

Tell me if you still have any problems after that, and I'll send you a different bootdisk image.
