GetHostByName error

[Alexey V. Abashkin]

Hi, SaMBa gurus!
Sorry, if it a dumb question, but
I  had  install the samba 1.9.18p1 on my BSDi2.0.1 box (previous
version was 17p4 and it work fine) and when I try to connect to Win95
or WinNT

smbclient \\\\HostA\\ServiceB <my password>

it say me next:

Added interface ip=xxx.yy.zz.aa bcast=xxx.yy.zz.bb nmask=255.255.255.240
Get_Hostbyname: Unknown host HOSTA.

but  HostA  was online in this local LAN and service ServiceB as
share  was presentable.
Any ideas?
If it need then that my smb.conf
----------------------------begin smb.conf---------------------
