strange networking issue


S

simon whale

Hi all,

stragne problem, one owrkstation, w2k prof service pack 4 and patched upto
date. recently while trying to browse the network, shows that there is no
computers on the network.

Domain
1 DC windows 2000, this is the primary DC and holds all of the FSMO roles
1 DC Windows 2003, this is a secondary DC and runs exchange 2003.
6 w2k prof clients
1 xp client

both servers are DNS servers.

on the client i can perform the follwing diagnostics

nslookup, and can query and machine on the network.
ping each machine on the network and get back positive results
when i run netdiag i get the following info returned

i using nslookup find all machines in our network with no error messages.
i can ping every machine on the network and use UNC path names no problem.
have also run netdiag, this shows the following below

please note on this machine i am also running VMWARE workstation. hence the
report shows three netowrk cards, when physically there is only one!

i think and this is a stab in the dark but i thing the problem has something
to do with the NetBT bindings?

if any body can point me in the irght direction to solving this problem i
would be grateful.

Many thanks
Simon Whale

I had a similar problem once and found that there was a system on the local
network that was configured to act as the mater browser. We could only see
domains/systems that the user had manually set up on his PC. Something to
consider anyway.

This is a netbios browsing problem so DNS isn't the culprit. If you are in a routed environment, it could be a WINS issue. If it's a
flat subnet, then WINS doesn't play a big role. The things to look out for are, multihomed DCs, multiple protocols on the wire and
firewall software. Any of these will cause the problem you mention. The best thing to do is to get the browstat.exe utility from the
Windows 2000 server support tools. Use this to determine who the master browsers and back up browsers are on the network.
The Domain Master browser must be the box running the PDC FSMO role. The other DCs will be backup browsers. For more
details on troubleshooting browsing problems refer to 188305 Troubleshooting the Microsoft Computer Browser Service

Micheal,

Thanks for your time. i have just tested this on three machines by enabling
Netbois over TCP/IP. but reading the Microsoft Press book for the exam
70-216, it states that you don't need WINS in a Windows 2000 or greater
network! or have i just turned too much off!?!

Many thanks
Simon

RJ,

TPC/IP, but i have not rebuilt the WINS server.
