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 (0x2) 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.
This problem occurs if the DHCP Client service on a Windows Vista-based client computer does not have permission to write the following registry subkey:
This registry subkey controls the client node type. If a computer cannot write this registry subkey, the computer uses a default configuration that is based on the following principles:
