You have two computers, both running Windows XP.
You ran the networking wizard on computer number 1 and selected the option to make a floppy disk that you could use on computer number 2.
When you try to run the disk on computer number 2 it doesn't work.
Is that it?
You don't need to run the floppy - you can easily run the wizard on the second computer. Provided you enter the same workgroup name that you used for the first machine ( by default it's MSHOME), and on each machine you enable sharing on the files and/or folders that you want to access it should all work. Give it a try.
