I need to change the NetBIOS Name under "System Preferences" -> "Network" -> "Advanced..." -> "WINS"; but I can click Ok, Apply or whatever; the OS will completely ignore my entry and keep the previous (default?) name.
Why the UI is broken? Why can't I set a different NetBIOS name from there? And how can I set it then?
The UI doesn't show the change and will restore the previous value all the time I come back. But if I just change the value, "Apply" and close the window, then after a while the value I inserted will be taken in account and will be shown correctly. There's no logic in this, but just try to save the value, close, and come back in 3/5 minutes (rather than immediately) to check if now the change is there. It worked for me.
However, trying to trigger the name change I also touched the other fields and added a WINS server with IP "126.96.36.199". That had the same problem. But now also that one has been saved, together with the name and, no matter how much I try to delete that entry and wait for the change, that non-existent IP is always restored and I am no more able to have the "WINS Servers" list empty.
Does anybody has any suggestion? The UI carries this "completely broken" feeling and I dunno if I am incurring in a bug, if I am missing something, or if at Apple are lazy and sloppy on power-user features 🙁
