Novell Read/Write replica

run nds manager (sys\public\win32\ndsmgr32.exe). then (from novell's help):
1. Select the partition that you want to replicate on a server.
2. Click Add replica .
3. Click the browse button to select the server to place the replica on.
4. Selectthe NetWare* Server object from the browser and click OK.
5. Select either Read/Write or Read-Only.
6. Click OK.
7. Confirm your request.

this will do it.

are you doing this under a login with sufficient rights? i'd login under an account with supervisor rights at the root - that way you're sure to have enough rights.

hope this helps!

You can certainly have more than 3 replicas of a partition. It is *not* the maximum, it is just the recommended best compromise for resilience over performance. If you only have a small partition, with good links between servers, whack a replica on the other two anyway. I use this setup, with two replicas being held on remote sites, in other containers. It doesn't slow down much and gives me peace of mind, in case my site disappears (!).
Anyway, the first answer was correct, I think you just chose the wrong window. You need to choose the *partition* and then File, Add Replica, not the server. Obviously, your user will need to have supervisory NDS rights at the container level to do this (doesn't have to be [root] supervisor, if it isn't the root you're replicating.
