public key not matching the one certified?

Hello All,

I have a Domino 6.5.2 running on SuSE Enterprise 8.0.
Actually, its data directory is
rectreated from a backup dump of one old server. So I
just did a DNS change and new server
started working fine. It also have a cluster
configured. So I just wanted to add one more

server to cluster. So I registered a server, created
the key. Certified the key.

Then I started installing second server. I started
configuring it as an add on server.
Now when I show the key file (locally copied from the
main server). It starts the setup,

comes to 20% of setup process then says "The public
key that is being used does not match

the one that was certified. Check the local logs for
details"

Also now when i register new users and when they try to login they get the
same error.
So is there any problem with my public key? Do i need
to regenrated the keys and id files?

any advice/clue?

Thanks in advance.
