Dynamic DNS ??? default gateway ???

I am installing a new infrastructure in parallel to the current. And, at the
same time I am upgrading some of my servers. The only thing that links the
two networks together is some of the servers. I multi homed the servers
providing alternate IP address of the new network. Things were looking good
until the weekend. Nothing changed over the weekend but for some reason
users on the existing network were looking at the address on the new
network. The wins server was being populated with the new network
addresses.



1, The servers that are multi homed are 2000 and nt4. I did not set the
default gateway on the 2000 servers, and did not set the wins address.
However I do not know how to (or know) if you can identify a different
default gateway of the second NIC on the NT4 servers. All but one will be
replaced on the new network.



2, The Wins server is a 2003 box. I am not sure if the Dynamic DNS might
have caused this. I think I read somewhere that Dynamic DNS takes the place
of some of the WINs functions.



Could the Dynamic DNS or the default gateway be causing this issue? For the
time being the I entered static mappings in the WINs server for the servers
effected. Which seemed to have worked for now..



Any thought would be appreciated
 
I don't think this had anyhting to do with the default gateway or dns. The
default gateway is just the IP address that computers send traffic to when
it is not on their network and there is no static route for the network
traffic in their routing table. You should generally have only one default
gateway assigned to the "computer" . Windows can only use one default
gateway at a time. Another one would only be available for dead gateway
detection in case the current default gateway does not respond.

Dynamic dns is used to dynamically register dns host records in the dns zone
for the domain. If you have multiple nics in a computer disable netbios over
tcp/ip on the nic that you do not want to register in the wins database in
tcp/ip properties for the nic in advanced/wins. Nbtstat -n will show current
netbios name registrations for a computer. A computer must be a wins client
to register or use the wins database. Ipconfig /all would be a way to see if
a computer is configured to use a wins server. --- Steve
