cannot create a datasource from ColdFusion admin

Dear All, In the new architecture design, the coldfusion server is located on a server in DMZ in the public domain. The sql server is in the internal netwok. I am unable to create a datasource from coldfusion admin page to the sql server 2005 instance that I am running on the server that is not in the dmz. please note that I have two instances of sql server installed on the server, 2000 default instance and 2005 named instance. i am unable to ping the named instance or create a datasource. i am able to ping and create a datasource to the default instance. please advise on what are the steps to create a datasource from coldfusion (in dmz) to a sql server which is not in the dmz. i get an error saying that either the login info is incorrect or the server does not exist. best regards, DA Note: The CF server is CF 8 I agree with the 1 to 2 seconds on Broadband. I allow 10 seconds on my phone. Its all to do with how long you think it *should* take. I just though I would share with everyone a really interesting page on the   android website. http://code.google.com/android/toolbox/philosophy.html    . It talks about fast, efficient, and seamless code. I think its well worth a read. Cheers, Joel

Find out what port your named instance is using, then create a firewall rule to allow your CF server to connect using that port. Dave Watts, CTO, Fig Leaf Software
