[CentOS] samba centos and cups client errors

Hello, I have a CentOS 4.4 box acting as a print server with a cups backend and samba 3.2.4. I recently ran yum which updated both cups and cups-libs, but i do not think this is my problem. I've added windows drivers to the samba sharea and have in the past printed a test page to the printer. Now when i atempt to do this with a word document from a windows box, i am getting the error: client not authorized. It is showing me connecting to the print$ share as my user which have SePrintOperatorPrivilege, then i get the error from cups about the client not being authorized. Any help appreciated. Thanks. Dave.
