Right-oh, can't make a local user with AD installed, domain only.
Tried specifying domain in command line mount but no difference.
Yes I could copy files to the smbmount/mountname dir from win & FC5.
COPIED iso to folder in smbmount. Ran the regular mount iso9660 from command line and it mounted in WINXP fine. Even showed as mounted in OS page.
Now I just need command lines that will create the other folders and make a boot image, please.
