It works for me: If I set register Level=Read in the access groups, I cannot copy (via "duplicate" menu item) that register neither from browse nor from a inspect window.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
