Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

As the NetBIOS protocol acts on Layer 2 and so is not routable, In order to enable network browsing of remote networks, WINS has been installed and configured on two domain controllers, both of which are on different networks.

The WINS servers seem to be replicating with eachother, and each has 127.0.0.1 set as the Primary WINS Server in each of their LAN interface properties, with nothing entered for Secondary WINS Server.

The DC which holds the PDC Emulator FSMO role has the Computer Browser service running and set to Auto start, and it has the WINS/NBT node type network setting at 0x8 (H-node - Hybrid node).

Remote network browsing does not work.

Is the WINS/NBT node type correct for this scenario? The reason why I think it may not be the right one is because I set the DHCP Server's 046 WINS/NBT node type option to 0x8 as well, after which the DHCP clients started to disappear from the Network folders. When that option is not set, does it default to B-node (Broadcast node)?

Or could it be a problem with the WINS servers setup?

any reason not to use DNS? –  Mathias R. Jessen Apr 8 '12 at 12:15
    
@MathiasR.Jessen: DNS is being used of course - it's an Active Directory domain, but WINS is still needed to browse other subnets, apparently (Network - the thing that used to be called My Network Places and Network Neighborhood). –  paradroid Apr 8 '12 at 12:50

1 Answer 1

NetBIOS doesn't act at layer 2, it acts at layer 3. It is not a network protocol, it's a programming API. NetBIOS requires a network layer protocol to transport it, such as TCP or NetBEUI.

Have you configured your DHCP options to assign the WINS servers to the DHCP clients? If not, then that's your problem.

Have you configured the WINS servers as push/pull partners? If not, you should do so.

I see. Well, how come it cannot traverse broadcast domains and one has to use WINS then? I suppose I need to read up about that. Anyway, I have already set option 044 in DHCP options (as well as 003, 006, 015 (and 046 as I mentioned above). This problem is also occurring with servers with static IP addresses. It's is just through the DHCP setting that I have realised that point-to-point from WINS is not working, and it is not attempting Broadcast, which I would have thought should happen. –  paradroid Apr 8 '12 at 12:11
    
I also have the WINS servers push/pull replicating, but it would appear that there is some sort of problem with WINS. –  paradroid Apr 8 '12 at 12:11
    
All clients (workstations and servers) that require network browsing across subnets will need to be configured to use the WINS servers. Also, have a read here: technet.microsoft.com/en-us/library/bb727015.aspx –  joeqwerty Apr 8 '12 at 12:22
    
All hosts have WINS Server details in the connection properties. I had a look through the linked page, but I cannot figure out what could be wrong. –  paradroid Apr 8 '12 at 12:48
