DPWS service host

When hosting a DPWS service on the AMI board you need to set the On-Chip RTC to a valid date/time - e.g. by reading out the battery buffered RTC on boot (see below) or by a NTP client (see NtpClient class and RealTimeClockSample 1.0.6)

public static void Main()

{

using (RealtimeClock rtc = new RealtimeClock())

{

// Debug.Print("DT Now=" + DateTime.Now);

DateTime now = rtc.GetDateTime();

// Debug.Print("RTC Now=" + now);

Utility.SetLocalTime(now);

// Debug.Print("DT Now=" + DateTime.Now);

}

Reason is that the Ethernet driver uses the on-chip RTC to calculate InstanceIDs. This can fail and return negative InstanceIDs and keep Vista from showing the AMI device in the network neighbourhood.

PS: You will also need the AMI V 1.0.0.2 binaries when hosting a DPWS service because this release fixes a bug in the Ethernet driver. The NtpClient class can be found in SDK Version 1.0.6. See registered downloads for both!
