DNSSEC and EDNS0 support

I'm testing DNSSEC using Windows 2008 R2 and Windows 7.  I have multiple virtual systems configured, some of which have signed zones and some which don't.  I'm trying to initiate a secure query from a Windows 7 system.  I updated the NRPT on the device to enable DNSSEC, but when i capture DNS data, the EDNS0 OPT record is not included and the DNS server responds as though the request was from a client that is not security aware.  Is there something besides the NRPT update required on the Windows 7 client to enable secure DNS requests?
