WINS Client Using DHCP


You can manually configure clients to use the WINS server

But using DHCP for WINS client configuration is much easier. The scope options within DHCP control what settings to give DHCP clients along with the IP address. One of the options it allows you to configure is the 044 WINS/NBNS Servers option. This option allows you to assign the IP address of multiple WINS servers. All that you have to do here is enter the IP address or addresses of the WINS server the clients will point to for NetBIOS name registration and resolution, click Add and then click OK.

Configuring the WINS Client Using DHCP

A second option is the 046 WINS/NBT Node Type setting, which is used to set the node type for the client. The node type is how the client handles NetBIOS name resolution. The node types are B-node, P-node, M-node and H-node. In order to set the node type you have to assign a numeric value based on the information that you see on the configuration screen.

B- Node

The B in B-node (0x1) stands for broadcast. Any computer set up as a B-node client, will send broadcasts out over the network to try and resolve NetBIOS names to IP addresses. The problem with using B-node is that it will create lots of traffic on your network and the NetBIOS broadcasts will not be able to pass through routers to other segments of your network.

P- Node

The P in P-node (0x2) stands for point-to-point, meaning the client will point directly to a name server in order to resolve NetBIOS names to IP addresses. The problem with P-node clients is choosing which name server to point to and if that name server doesn’t contain the answer for the resolution there is no other way to resolve the NetBIOS name. Broadcasting is not used with P-node.

M- Node

The M in M-node (0x4) stands for mixed; it’s a combination of the B-node and the P-node. When a client is set to M-node it will first send out a broadcast, if the broadcast fails it will then try to communicate with a name server to resolve the NetBIOS name to an IP address. The problem with using M-node is that it will first broadcast on the network before communicating with the name server directly to resolve the Net BIOS name, which will create more traffic on the network.

H- Node

The H in H-node (0x8) stands for hybrid; it’s similar to the M-node in that it combines the B-node and P-node. The difference is that it will first communicate with the name server to try to resolve the NetBIOS name to an IP address and then send out a broadcast if the name server fails to resolve the NetBIOS name. WINS clients that are manually configured, default to H-node, and this setting is typically used within the company network as well.
