I spent some time trying to configure Samba 1.9.17pxx on SunOS 4.1.3 and 4.1.2 without success. On Solaris 2.5 it's OK. After a while I went back to 1.9.16p11 for the SunOS machines and it worked again. The message I was having on the 4.1.X was the one about "unfriendly server software". Besides that everything's fine, Patrick Groeneveld
