Samba - Win 98 clients

Have the same problem with Samba on Suse 8.2 at our office and Suse 9.1 at our client's office. Adding SECURITY = SHARE in smb.conf allows all the XP clients to see the Samba share but none of the Win 98 clients. Since those Win 98 clients can currently see the Samba shares on an older Sun Solaris box I'm assuming I didn't set something necessary in smb.conf for Suse. Any suggestions? jcp
