nethood invisible while Samba is local master

[Maciek Uhlig]

Could somebody kindly make a comment on the following problem:

Samba 1.9.18p4 runs on a Solaris server and there are some W95 PCs around. 
Samba is configured with:

domain master = yes
local master = no
preferred master = no

OK, Samba server and all PCs are clearly visible in Windows NetHood. 

Now, I change configuration to:

domain master = yes
local master = yes
preferred master = yes

Samba's nmbd becomes then local master browser for workgroup. At this moment 
Samba server and all PCs vanish from Windows NetHood.

Beside that all works well (i.e. domain logons, finding shares, etc.). Only 
browsing is corrupted. Is it a bug|feature of Samba or what?
