If you have ever wondered about the WINS Node Type setting on your DHCP configuration as I have you may appreciate the following (perhaps slightly flippant!) explanation Gary Wisniewski sent me on what the various settings mean (NT provides no details on this).
You might also find it helps resolve problems where you cannot find other PCs on a network.
Some may even find it amusing...

Broadcast, Point-to-point, Multimode, Hybrid

B-Node, P-Node, M-Mode, H-Node

B-Node: 0x1
  Broadcast over the net as the only means of resolving NetBIOS names.
P-Node: 0x2
  Assume a point-to-point connection to a WINS server is the only means of resolving names on the network.
M-Node: 0x4
  Broadcast first, then use WINS upon failure. Local names will thus always be found using broadcast, at the expense of significant extra network traffic.
H-Node: 0x8
  Use WINS first, then broadcast upon failure. All names will be found using WINS, except names which are very new and haven't yet made it into WINS, or names on the LAN which aren't configured for WINS.

If you want to play it safe, but have a good working network, use H-Nodes.

If you really don't trust WINS, and don't really care if your network works well, use M-Nodes.

If you run a tight ship, and demand purity and efficiency, use P-Nodes.

If you don't want to use WINS, use B-Nodes, but then of course that means that you're using DHCP and have an NT Server and are configuring it not to use WINS even though you certainly should know better since you're using DHCP anyway, and since you have gone to the trouble to figure out what these node types mean, and thus should require only minimal intelligence in order to know that you SHOULD be using WINS and thus I conclude that the B-Node setting is only used by the stupid.

I don't know where to find this information and I've never seen good documentation on it, especially the last bit.

Boy at Pub: "So, where do you work?"
Girl: "I'm a programmer."
Boy: "Really? I use computers too!"
Girl: "Ever use B-Nodes?"
Boy: "All the time!"
Girl: [throws up]
