With only the information you have supplied, it is impossible to say
what might be causing your problem. My best guess is that you have made
an error in coding your client module. First, use snoop, tcpdump or
some similar tool to verify that your client is actually sending a
request packet to the server. Next, verify that this packet is
correctly formatted and that the contents are valid.

If these steps do not lead to a solution perhaps you can post again and
furnish more details.

In addition to Richard's suggestions, if it's not a coding error, perhaps
your software firewall is blocking the program because its signature has
changed (due to re-compiling). Does the server respond to NTPQ commands?

Source code, no, but a simple Windows executable can be found here:
