Is it all clients?
I have a Hotel that runs on that Version. All windows, on their onsite server. So I doubt it is the version.
Can you send me logs on the Server and Client side?
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...
