samba - Jun 2005 - What's service 2227a280-3aea-1069-a2de-08002b30309d?

Hello samba,

  I  have  a  samba  3.0.9  server  that shares printers using SPOOLSS and
  hosting  the  drivers. Everything works, but accessing the printers from
  Win XP is very slow and I get an error in the log that says:

    couldn't find service::{2227a280-3aea-1069-a2de-08002b30309d}

  every time I try to access the printers list for the server from WinXP.

  Is this a known problem? What's this service that winXP does not find?
