HiLo sagem GPRS Dns error from php script

Hello I am currently using the HiLo Sagem GPRS module

My problem is concerning connecting to the internet.

I can run through the tutorials ok and connect to google however whenever I try to connect to a php script on my server (e.g test.myserver.com/up.php?DID=1)

I receive a DNS error KTCPNOTIF: 1,3

Does anyone know how to resolve this issue? (will I have to think of a different way of sending data to the server? )
