duplicate name error

[Burnie]

We have several Windows 2000 Servers that have two nics in
them. One nic is for the primary network. The other nic
is for the "shadow network". We wanted it this way so
when the servers communicate with each other, they would
use this secondary network to do so. The primary network
is 10.1.1.x and the secondary network is 172.16.1.x. We
have a entries for every server that is on the secondary
network in each host file. When we reboot the machine we
get a duplicate name exists on the network error and is
not allowed to join the domain. Does anyone know how to
resolve this issue?

On one of the NICs on each machine, the 'shadow' NIC, disable NetBIOS, MS
Client and F&P Services and the dupe name will go away.

This is regarding your reply: "On one of the NICs on each

F&P Services and the dupe name will go away."

This doesn't work. First of all, I had already tried
these things. Just to make sure they were still set that
way, I checked again. Still getting the duplicate name
message. I have noticed that a lot of people have asked
this same question other places around the net. I have
yet to find anyone that can solve this problem. If anyone
knows, please let us know.
thanks,
Burnie.

This usually kills the dupe name error. Are you using WINS? Dupe entry in
the WINS database? Is RRAS configured for routing?

I found several other postings saying what fixed their
problem. Whether it was changing an entry in the
registry, unchecking a box in the network properties, or
changing a setting somewhere. Trust me I tried them all.
Then I saw someone post something about WINS and it got me
thinking. What I did was just take out all static WINS
entries on the machine having the problem and the
duplicate name error is no more. I am still able to
resolve names, so I am happy. I just wanted to let you
know. Thanks. -Burnie

No problem. I don't know if it was my post about WINS or someone elses,
either way, glad it helped resolve the issues!
