Using MS Win 2008R2 as NTP server

Hello!

I  have Windows Server 2008 R2 SP1 Domain Controller with NTP services, I setup NTP on server as described at this article

http://support.microsoft.com/kb/816042. So, as I understand, my server act as realy NTP (not SNTP) server.

But Cisco switch (Cisco 3112) can not sync time with this server.

Can anybody help me to fix problem?
