You use a Dynamic Host Configuration Protocol (DHCP) server to assign TCP/IP configurations to client computers. You set the WINS/NBT Node Type scope option to a specific node type. However, one or more Windows Vista-based client computers do not use the node type that you specify for name resolution.

For example, you set the WINS/NBT Node Type scope option to P-node (0×2) to configure client computers to use P-node name resolution. However, some Windows Vista-based client computers do not use P-node name resolution. Instead, if these computers cannot resolve the host name by using a NetBIOS name server, they broadcast requests. This behavior causes unexpected traffic in the network environment.

Note: In the P-node configuration, client computers should not broadcast requests even if the computers cannot resolve the host name by using a NetBIOS name server.
