Hello We are running Samba on 5 PC (linux) fileserver on our 300 PC network for 2 years now and everything is fine. As we have added 15 Sun (Solaris 2.7) workstations, I set up Samba 2.0.6 on them. It runs fine but when I cannot make it work to receive popup-style message. Sending is ok, but when receiving I've got the following trace : [1999/12/01 09:57:09, 10] lib/util.c:(2980) [000] 04 50 47 55 00 04 57 4D 53 2D 55 58 31 30 00 01 .PGU..WM S-UX10..

I've tried the binaries distribution of samba and also I've recompiled the sources with the same result Thank you for your help Philippe
