Weird problems with Samba 2.2.8 under Solaris 8 + latest kernel patch

[Pierre Belanger]

Hi,

Quick follow up... the problem was on another server. After the last 
reboot, not too long ago, "fast-ethernet" negotiation between the
Cisco switch and the Sun server did not work properly. Cisco switch
negotiated at 100Mbps/full and the Sun server in half duplex.
