Network Neighborhood Browsing Sudden Change

Hi All,

We have a fairly large win2k rollout (WAN with multiple facilities) with 2 wins servers on a single AD domain that replicate to eachother.  Over the passed couple of weeks we've noticed that we can no longer browse anything but local subnets no matter what branch we are at even though the WINS settings are correct.  Any ideas on why NN wouldn't show all machines in the domain???  Thanks!

Can you still communicate to other machines using netbios names?

find a tool called "browstat.exe" and run it with /status flag - it'll help you find out which computer is the Master Browser (MB). It is possible, that some unexpected computer is winning elections and becomes the MB.
With this browstat you can find lots of interesting things about your browsing environment.
Another possible problem that I can think of, is that either the computers' node type has changed to "broadcast".

As for a more serious debugging, install a network monitor (ethereal + WinPcap) and run it while trying to browse the net. Analyze the traffic - the info in ethereal should help you see where delays occur - a good pointer to the dropped packet.

You can also run a "net use" command from cmd it's a dos version of NN.

Is DNS working correctly still?

Try doing IPCONFIG /FLUSHDNS on a client and then IPCONFIG /REGISTERDNS.

Seems to work and no error in event logs.  Also, all internal ping / nslookup commands work fine.

When you say ping commands work, I assume you are pinging local and remote, and Ip address' as well as Hostnames, correct? All return properly?
Are the WINS servers WINS clients?
Are they configured static or DHCP?
I assume you are using DHCP, do you have the WINS configured at the scope?
Silly questions, but still pertinent.
Since you are an AD domain, why WINS? What are your clients? And are the Servers able to browse across the subnets?
