I've got a CentOS 4 print server with a deskjet 5150 printer attached to it. I've installed samba 3.0.24 on this box and am atempting to upload printer I've created a raw queue in cups and went to the print server/printer and faxes on an xpsp2 box. I then right click on the printer, i get a dialog box saying that no printer drivers are available and i'm asked if i want to add one. Depending on what i choose two different things happen. If i say yes, i know this isn't right, i am taken to the apw and can browse to the drivers and add them. Following that and going back to the printer i select it again and get the same dialog box about no drivers being available, obviously selecting yes didn't work. If i select no, as stated in the howto, i then go to the advanced tab of the resulting dialog box. I do not see a new driver button, it is not there. I am unable to add these drivers via pointprint. In my samba logs i see:

I've confirmed the user atempting to add the drivers is in the correct group and it's not a permissions issue. I can navigate to the share and manually create files and folders.
