Interestingly I went into it's setup and found that it has it's own section for SNTP. On the laptop XP pro seems to be able to keep the correct time, maybe it is using the time in the router. I don't know. Also I checked the firewall packet filter settings and UDP port 123~123 is enabled, and so NTP on the OS/2 desktop should work. Needs more work to find out what is wrong.

Anyway when I got to read the user manual, I can take a guess at what is happening. I presume you are using this device as your DHCP server and the windoze box is taking all of its configuration (including Time server from the data sent to it). Under OS/2 I don't believe the DHCP client picks up the SNTP server address and you will have entered it manually. I believe the router will also be running as both a DNS and a SNTP proxy, meaning, you should be able to set the OS/2 or eCS SNTP server settings to the IP address of the router and it should pass the required data through. If this works, try changing your DNS settings also to the router. Once you have configured the router to point at your required SNTP and DNS servers - let it proxy the work for you - this will reduce your network traffic to and from your ISP and hence costs. Cheers/2 Ed. ----------------------------------------------------------------------------------
