ID Vault Replication

I have created a vault on our Administration Server. I now want to replicate it to another server. I use the ID Vaults - Manage tool to create the new replica. I select the server and type the vault password when prompted. I then receive this message:

YOU HAVE COMPLETED THE MANAGEMENT OF THE NOTES ID VAULT ‘/ADMINVAULT’ WITH WARNINGS.

In the process of managing the vault the following tasks have been run.

Add the following servers as vault hosts:

    COULD NOT ADD SERVERNAME/OU/O. (REMOTE SYSTEM NO LONGER RESPONDING)

However, the remote server is indeed up and running and accessible (and in the same Domino Domain). Is this a known problem or have I done something wrong?

Thanks.

Subject: Never mind…

I just realized the server I want to replicate with is not at version 8.5, yet…
