Samba doesn't work as I expect

Attaching to a Win98SE share. The share is set as: name: test$ users: Administrator Full Access Domain Users Read-Only Lab Group Full Access The World Read-Only I mount the share with: mount -t smbfs -o username=administrator //<sys name>/test$ /mnt/test which presents me with a password, which I enter the (domains) Administrators password, which works and the contents of the share are in /mnt/test. A look at the files shows all files have -rwx------ and all dirs have drwx------, and that the ownership is root:root (and I'm logged in as root). However, I am not able to create or alter anything in the subdir. Unless, I change "The World" to "Full Access", then I can create and alter. What am I doing wrong?
