I don't know much about the AOI. However, the IP address it request should be quite self-explanatory. It's whatever the IP address for your NTP server.
Any Windows machine can be a NTP server. I have found that sometime they tend to be a bit flaky though. I very much doubt it would work on a emulator.
Sorry, I don't have much experience with NTP. The IP of the Server is the same as the source IP, correct? For some reason I keep on getting a WriteSocket or ReadSocket error depending on what IP address I use.
Has anyone encountered a similar error?
