Access denied, unable to access the printer (Trust Credentials)

I have a shared printer on a windows 2000 pro computer. I
have 5 others windows xp computers (3 home edition), 2
(xp pro edition) all in the same network. I sucesfully
connect all of them to the printer using the printer
wizard. My problem: every time I logoff/log back in from
any of the XP HOME ONLY computers it shows me "Unable to
connect , access denied in the printer" queue. It looks
like doesn't hold the user/password (trust credentials).
If I recreate the printer it will work until the next
shutdown or logoff.
Note: I always clicked "Save password" on the password
dialogue box.
Any idea what I am I doing wrong ?, I research the whole
Microsoft Knowdlege database finding only article. #
307053 with no solution so far.
Any suggestion will be appreciated.

Thank you
