Environment:two subnet 192.168.0.x,192.168.10.x
DHCP,WINS was installed,both work normally.
TCP/IP was installed.can ping each computer of other domain.
How can computers in both subnet can browse computers in another subnet?

Do you have two wins servers or one?

One suggestion, for starters is to just have one, for now.

Are these computers in the same NT Domain?

Again I am assuming yes.

Assuming PDC on subnet A

Set up DNS and WINS in the same subnet. Since you have to subnet A will be 192.168.0.x mask 255.255.255.0

Set up your wins server and dns server (can be the same box, that is how I have my company network setup)

Server 1 in subnet A is DNS/WINS, on the wins tab in the TCPIP properties,check the enable DNS lookup for Netbios resolution

in the zone file for your domain in dns ensure that the properties for the zone allow wins lookups in a dns entry is not found.

in the dhcp scope options for subnet A have these options
router 192.168.0.1 (use your routers address)
DNS servers use your dns/wins server address here
WINS servers (option 44) use your dns/wins server address here
Wins node-type set this to 0x8 for hybrid

(all ip addresses for this dhcp scope should reside on subnet a)

for subnet b dhcp options
router 192.168.10.1 (or whatever you are using)
dns servers use your subnet A address here
wins servers users your subnet a address here
wins node-type 0x8 for hybrid.

Also if you are using a single domain, you will need a BDC on the subnet b to keep the domain browse list.

I have this implemented for 60 offices and having the dns name resolution really increases response time.

"wins node-type 0x8 for hybrid. "
Is this important?
All settings was set just like you mentioned except this one.
And,some clients(win2000,win9 use static Ip,I can't find releated settings in WINS tab.

1.One domain.
2.Two subnet share the same WINS Server.(win2000)
3.Search-computer,can find computer of another subnet,but can't find it in network neighbor.
4.Some clients use Dynamic IP,some use Static IP.

The node type could possibly be a problem, but only for those workstations that are not using DHCP, assuming you have set the DHCP scope options correctly for h-node type. Supposedly, all Win9x, NT or 2000 workstations will default to h-node if youhave WINS enabled, but I'm not sure I'd trust this. You can check in the registry at HKLM/System/Current Control Set/Services/NetBT/Parameters and look for a paramater called "NodeType" or "DHCPNodeType". The hex value should be 0x8 for h-node. It seems likely, however, that there is something wrong in either your WINS or DNS settings, or it's simply a lack of a master browser for one segment of your network. Can you ping by name as well as by IP? If the answer is "yes," then the problem is probably one of master browser settings rather than IP routing or DNS/WINS settings. Hope this helps!

The node type is important. If you do not fill in the wins information on the wins tab of your static ip machines, they will only broadcast to resolve netbios names. If you fill in the wins server addresses on the wins tab, your node type is set to hybrid, check it out by running ipconfig /all at a command prompt. The line node type will be either broadcast or hybrid. you could run winipcfg on the 98 box and click on the more details button.

If you are trying to see computers listed in your network neighborhood, you will need to have a browse master per subnet to maintain the browse list, and that machine will have to be listed in the wins server as a browse master. so that when a machine requests a browse list from the network, itchecks the wins server for a browse master on its subnet. The easiest way to do this is setup a BDC on the second subnet.

Thanks,I've checked the node type,and the default type is 0x8.
I believe my problem is a browse list problem.(wins resolution must be ok).
As you mentioned,How to register my browse master in my wins server as a browse?
(My browse master usually is my PDC,with two NIC,connected to the two subnets)
your great help will be appreciated.

I've checked my Wins Database.
and find one record was marked as Browse Master.But the record name is my domian name(or my workgroup name)and the corresponding IP is my PDC's IP,is it ok?or how should I modify it?
Another:I wonder if I disable oneNIC on PDC,and put BDC into another subnet,dose it help?

Place a BDC in the second subnet, remove the second nic from your PDC. Synchronize the entire domain, wait 15minutes your second subnet should be able to retrieve a browse list from the BDC.

Just some information about browse lists. A browse master on a given subnet broadcasts a request for all computer to respond with domain/workgroup and computer name, it collects that information and waits for the domain master browser to request its (the subnet browse master) browse list. The domain master browser then collects all browse lists for all browse masters that it knows about collates the lists and then rebroadcasts the list down to the browse masters. Having a BDC on a subnet without a PDC will insure that the BDC (default configuration, no registry "tweaking") is always the master browser for that subnet. By default when a BDC starts up it checks to see if there is a browse master on the subnet, if there is an election if held and if a PDC exists on the same subnet the PDC always wins, but if another BDC already exists the one that has been active the longest wins the browse master election, if a win9x box is browse master already, the BDC wins the election, as part of the startup after the election, it registers with the primary wins server as a browse master (0x020 record in wins)

Hope this helps.
