Deleting a Read/Write Replica that does

Hello- I am in the process of trying to delete a R/W Replica that does not exist on our tree any more. I am using NDS Manager to delete but it gives me a 626 error, basically telling me that the server is not there. The server the Master Replica ison is running Netware 5 SP3a and the one I am trying to delete had the same except it had SP2a. Is there a way I can still delete that server even though it does not exist?
Any help would be appreciated!!!

Thanks,

Tammy
