I downloaded the update installer from LCS, started it, accepted the license terms, selected "Download and install updates", clicked Next and it reports "No internet connection found. Please verify that your internet connection is available."
Since I had just downloaded it, and am now posting this message from the same machine, my internet connection is clearly working perfectly. So presumably, what it really means is "the installer can't connect to the specific host and port it needs to access."
How do I find out what it's trying to do short of running a network sniffer? Which host/port is it trying to reach?
Or can I just download the cumulative updates from somewhere else?
