Can't Send Net Messages Over WAN

[Mark McCurdy]

We are full Active Directory running WINS and DNS servers.

When we send a Net Message to the domain it will only go the branch office
from where it was sent. It used to travel to all the servers/workstations
in our domain. Any thoughts as to what the problem might be. We are a
single domain with no trusts. I still have IP traffic to all branches
obviously. I can ping by name and get the full (e-mail address removed) .

Thanks for you help,
Mark

Chance are you have one of the three following issues:

NetBios name resolution is incomplete (no replicated WINS servers)
Firewall is stopping the NetBIOS datagrams
Client machines are stopping them or have Messenger service disable
to prevent "message spam attacks".

Or more than one.

Hmmm strange. We have one WINS server in our Central office where all the
branch offices run into.

All the client machines are on because as I mentioned we can send it with in
offices. Very strange.

Thanks though....

Are ALL of the machines "WINS clients" of that WINS server?
(And can they reach it to register themselves.)

Although a single WINS server for a distributed network can be
made to work, it is generally not the best design.

Usual practice is one or more WINS server at each significant
location (site), and have them replicate -- as long as there are
not a large number of sites.

I think I will probably move to that model.

I did do a little research and I think it is my routes. I put in QoS for my
VoiP traffic a few weeks ago. I removed it and sure enough... messaging
came back.

Now I have to think of a way around this.
