Hello Jim,
How are the DNS settings on the NIC for the servers? Check if the servers having the ones that are not to add listet as DNS server on the NIC.

Hello,
I currently have 4 DNS servers in my office. I'm having an issue
where I
can see some, but not all , of the other DNS server from the DNS
Manager
console from each machine. But there is no logical pattern.
This table attempts to illustrate what I'm talking about. The table
shows, from each server (vertical letters) what other server can be
seen from the DNS Management console of that machine in a Yes / No
fashion.
All machines are Windows 2003 Domain Controller machines with at least
SP1. Server B and D are SP2. Dashes means the computer itself for
which each can obviously see.
Server A B C D
A - N Y Y
B N - Y Y
C N N - Y
D N N N -
To summarize in case the table doesn't come across clearly formatted:
Server A can successfully only add servers C & D to its DNS Manager
window.
Server B can successfully only add servers C & D to its DNS Manager
window.
Server C can successfully only add server D to its DNS Manager window.
Server D can NOT successfully add any servers to its DNS Manager
window.
When I write that the machine can not see the remote machine, I mean
that if, inside the DNS management window, if I right click on the DNS
text and click on Connect to DNS server, select connect to this
server, it will come back as "The Server Is Unavailable". If I add it
anyway, it will list the server with a red X. If I then click on the
server with the red X it expands to show the event log and I can see
the event log of the server it says it cannot connect to. The event
logs are very clean with no errors or warnings.
From each DNS Server machine, I can open a nslookup session and query
each of the servers that the DNS management tool says it can't connect
to without error. Each machine can ping each other machine. I can
telnet from each machine to each other machine.
Everything seems fine but the DNS manager just can't see any/all of
the other machines - just some.
Any ideas of what could be wrong?
Thanks
Jim
