Cisco :: Accessing Inside PAT From DMZ Network?

Setup as follows:

Cisco ASA 5510
Inside 172.17.101.249
outside 5.5.5.2
DMZ 192.168.100.1

I have an internal server 172.16.1.202 that is PAT to 5.5.5.103 to allow RDP connections. - This works fine from the internet.I have now been asked to allow our guest wireless (192.168.100.0/24 - DMZ) to access this same external connection.We have 2 cisco controllers, with the guest controller "anchored" in the DMZ.I cannot get this to work.Both the DMZ and inside NAT their internet connections to 5.5.5.2.
