Did you have any HAL customisations that would have affected this behaviour? I haven't heard of this problem before but I can look into it if you are able to provide me with backup that this might be repeatable in.
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...
