In case of 100% full in the print server desintation, removed a driver that was installed and then re-added the same driver using the Server Properties gui will failed.
Note: no additional driver is added in the meanwhile.
Seems like the 'Remove' of driver does not clear all the space enough for the same driver to be re-added.
It's discovered that after installing driver for non Win 2000 OS, the temp dir (i.e. '__SKIP_XXXX') is not removed. These dirs consumes 4KB each.
This is probably fixed with a newer Samba version. If you still see the error. Please open a new bug with 'debug level = 10' logfiles of the new Samba version 3.5 or 3.6. Thanks!
