If you’ve setup samba (rather than the builtin cifs/smb) chances are that you can only browse to your samba shares directly on IP only.
If you want your box “network browseable” you’ll need to load nmbd.
You can find a really good write up on modifiying the SMF for samba to autostart the required service here : http://wikis.sun.com/display/BigAdmin/Enabling+Browsing+with+Samba+in+Solaris+10+Update+4
