I am using DHCP Option Code 42 - NTP Server Address.
This means the SNTP server address is sent by the DHCP Server in Option 42 (see rfc 2132).
I can interpret this by regularly polling the registry but I wonder whether there is a way to subscribe to notifications if the NTP Server Address(es) is changed on the DHCP Server?
I think Windows proper might have DhcpRegisterParamChange() but WinCE 6.0 r3 doesn't seem to include this. I want similar behaviour to NorifyAddrChange().
Am I stuck with polling at regular intervals?

I ended up using CeFindFirstRegChange() and CeFindNextRegChange()
