Ken Barwicks tip works only if your AS/400 is on the same subnet as your PC. In many organizations it is not. You may want to try my tip.
1. Make sure your Win9X user profile is enabled on the AS/400.
2. Use OpNav to create a "share" of your AS/400. There can be shares of different directories, but still the use of files is limited to what your user profile can access. A sharename can be like: ROOTUPD for the whole AS/400, or HTTP for the HTTP-directory (if you have such an IFS directory.
3. In Map Network drive give a driveletter and a folder. The folder is specified with the IP-number (NOT THE NAME!) to your AS/400 and the sharename like 188.8.131.52rootupd.
