Clients missing from network neighbourhood

Clients missing from network neighbourhood

Clients missing from network neighbourhood

Hi all,

Apologies for the amount of content!
I have a current issue with getting clients into network neighbourhood that are located on the WAN.  Local clients are there and at the remote sites it is the same.  We have recently moved offices and changed some routers and connection equipment (too much to list but basically remote sites have CISCO 2600's and connect to a CISCO 7507 via Private circuits), before this move all clients were in network neighbourhood.
We are running Windows NT 4 (sp6a) domain using TCP/IP and NetBEUI, some remote sites have NT4 servers some don't but all clients log on to the domain okay and all are in the same workgroup.  DHCP and WINS are set up and working okay.  All clients can ping all clients by IP and Name.  All clients can also map to all clients.

The main reason for wanting clients in network neighbourhood is we need to point remote site to print to other remote sites in the very near future, this has to be done with "easy to talk though instruction" to none computer literate users.

Oh dear

Looks like I may never get this solved

RE: Clients missing from network neighbourhood

I think I now have the answer, for those of you who also have this issue, here is my conclusion:-

UDP Port 137 (NetBIOS Name Service Broadcasts) All NetBIOS over TCP/IP (NetBT) broadcasts are sent to the UDP port 137, which is defined as the NetBT Naming Service.  This usage is defined by Request for Comment (RFC) 1001 and 2002.  Routers normally filter out these frames because they are sent to the hardware and subnet broadcast address.  However, some routers allow all frames sent to a particular UDP port - which is used only by NetBT - to be forwarded.  As a result, the browser looks as if it is on one, big, network segment.

So the routers need configuring as above!
It's so easy when you know how.
