samba - Mar 2004 - winpopup and wins.dat

Hello.  I'm trying to automate some error reporting on tests run on our
labs, and I'd love to pop up messages on the users' screens when that
happens.  However, some of the computers in question don't have a
corresponding <03> section in the PDC's wins.dat file.  (Oh: Samba
2.2.8a,
under Debian.)

Any ideas as to why it wouldn't be there?  The clients are all W2K boxes...

Thanks,
