We encountered the following problem:
We have a mixed environment (R5/R6). The names.nsf on an R5 server went corrupt and the server could not be started anymore. We pulled a replica from a working R6 server to our local workstation (R6) with extention “.ns5”. Then we renamed the file to “.nsf” and copied it to the problem server (R5) - OS level.
Restarted the server. When accessing the server we got the following error "This database has local access protection and you are not authorized to access it locally
…"
Reason: On the R6 client by default all local replica’s made have “local medium encryption” (file - user security - notes data)
After selecting “Do no locally encrypt” and redo the procedure, everything went fine.
