HP Pro Curve 3800-48G-PoE DHCP Issue

Has anyone run into an issue whereby the HP Pro Curve just starts blocking/preventing clients and phones from local DHCP addresses from a Windows 2008R2 DHCP server? The DHCP server is working as it should. We just can't figure out how determine whether the Pro Curve is blocking or otherwise interrupting DHCP comunicatons across our network. The Pro Curves have been up for more than 250 days and DHCP has been working over that time. We h ave not made any other changes to the DHCP server or the domain in general.

Can you share your config? There is a feature called DHCP Snooping that is designed to protect against rogue DHCP servers.
