[Samba] Samba 3.0.20b and Win NT 4

[Den]

Hi.
There are Samba 3.0.20b and 'local master = yes'.
If I use WInXP or Win98, I can browse network. All is Ok.

But I am getting an error
"The server is not configured for transactions"
when I try to browse network with Windows NT 4.0. I can connect to
any PC(to Samba server also) on network by `\\PCNAME' command.
But can't browse network!

Could somebody help me?
Thank you.
