Question : Cannot browse computers on different subnets?
|
|
Hello,
I have been setting up a lab where I am experimenting with a WINS server. Please see diagram below. My goal is to beable to click on network neighborhood and see all workstations in Subnets A and B
Subnet A Description
Windows 2000 Server Netbios Name: Intel01
IP: 192.168.0.2
SNM: 255.255.255.0
DNS: 4.x.x.x
WINS Server: 192.168.5.2
Workgroup Name: IT
Workstation A
Netbios Name: michaelsroom
IP: 192.168.0.10
SNM: 255.255.255.0
DNS: 4.x.x.x
WINS Server: 192.168.5.2
Workgroup Name: IT
From Workstation A
I can do the following. I can browse machines via UNC and via IP on subnets A and B.
From Workstation A. I cannot browse network neighborhood and see other computers on Subnet B.
My WINS server is located on subnet B
Subnet B Description
Windows 2000 Server Netbios Name: IT01
IP: 192.168.5.2
SNM: 255.255.255.0
DNS: 4.x.x.x
WINS Server: 192.168.5.2
Workgroup Name: IT01
On my Wins server I can see registractions for workstation A and the 2000 server on subnet A.
I have been up here on google for the last 5 hours reading all about browser masters and netbios. I understand that each workgroup or domain needs to have a master browser. I believe that the server on subnet A is a browser Master because it is running the Computer Browser Service. The Wins server is a Master Browser because it says so right in the WINS dialog box ___MSBROWSE___01H Other.
Also I am running one more server on Subnet A called server2000 wihich is running active directory and the Domain it lives in is called server2000.local. Does this server cause any issues possibly.
please let me know if i am missing anything. Thank you very much for your patience and efforts.

I agree DNS is not an issue in is problem I feel but that if you don't forward netbios boardcast you wont fix the problem. I can configure the cisco 26xx router using:
conf# interterface ethernet 0
conf-if# ip helper-address x.x.x.x
You need to specify this command on the interfaces which are connected on different segments. the address is the address of the machine you want the boardcast to be sent. By default it forwards 8 different types of boardcast which are:
UDP Port Name
69 TFTP
67 BOOTP Client
68 BOOTP Server
37 Time Protocol
49 TACACS
53 DNS
137 NetBios
138 NetBios Datagram
So if you want to stop the forward of everything except Netbios then issue the command in global config:
conf# no ip forward-protocol udp 69
conf# no ip forward-protocol udp 67
conf# no ip forward-protocol udp 68
conf# no ip forward-protocol udp 37
conf# no ip forward-protocol udp 49
conf# no ip forward-protocol udp 53 <---- I would probably leave this one
This is the only way your problem.
