Hi,

I have a server with 2 NIC's we had our DSL connection go
down and come back up. the 2 nics are for internal and
external network. the internal nic is 192.168.0.199
(called Server1) and the external nic is 10.202.1.2 with a
gateway of 10.202.1.1.

when I ping server1. i get 10.202.1.2 and not
192.168.0.199 as I would expect.

I have looked in the DNS database and the computer name
Server1 has the IP of 10.202.1.2 next to it.

I want it to be 192.168.0.199

Can I just manually add a host ? do I have to get rid of
the old record ? are there any ramifications for doing
this ??

any help would be much appreciated.

Cheers

al.

In your DNS server property sheet on the interfaces tab enter your listener
IP of 192.168.0.199.
delete the record with 10.202.1.2 in DNS and restart Netlogon.

Then in control panel open your network properties in the Advanced menu,
select Advanced settings, move the interface with that IP on it to the top
of the list.
 
The other thing I do with multihomed machines where only one
should appear in the DNS is to give the "other NIC" a NIC
specific DNS name to register OR just tell it not to register the
other one (check box) and register only the one I prefer.

Example: My router to the internet registers the outside NICs,
as x.CABLE.LearnQuick.Com and x.DSL.LearnQuick.Com.

Cable and DSL are made up subdomain names on the respective
NICs.
 
In addition to what Kevin has suggested, open the properties of the LAN adapter that isn't registered in DNS. Open the properties if TCP/IP and go to the
Advanced properties. On the DNS tab verify that there is a check in "Register this connections addresses in DNS".

Thank you,
