Samba server domain name resolution Problems

Samba server domain name resolution problem-Linux general technology-Linux technology and application information, the following is a detailed description. Samba is successfully installed and configured without any problems. however, my windows Host Name is Beyond and the Working Group is workgroup. linux has also joined this Working Group. When I use linux to access windows, use this command: smbclient-L // 192.168.1.100/workspace: (100 is my windows Host IP address)
Password:
Domain = [MYGROUP] OS = [Unix] Server = [Samba 3.0.25-2. fc7]
Sharename Type Comment
-----------------------------------
Workspace Disk share workspace
IPC $ IPC
Session request to 192.168.1.100 failed (Called name not present)
Session request to 192 failed (Called name not present)
Domain = [BEYOND] OS = [Windows 5.1] Server = [Windws 2000 LAN Manager]

What makes me strange is that my windows Host Name is Beyond working group, but the "Domain = [BEYOND]" should be "Domain = [workgroup]" in the linux Command feedback.

My/etc/samba/smb. conf configuration is as follows:
[Global] Section
Workgroup = workgroup
Netbios name = liyu
Server string = my linux server
Security = share
Share resources
[Workspace]
Path =/home/liyu/workspace
Comment = share workspace
Public = yes

After the configuration is complete, run the following command:
# Service smb start
# Service nmb start
Started successfully!
Run the following command:
# Smbclient-L // 192.168.1.101/workspace (101 is the IP address of my linux host and the shared information is accessed)
Password:
Domain = [WORKGROUP] OS = [Unix] Server = [Samba 3.0.25-2. fc7]
