Using trusted database connection across domains



I have asked this before; however, I never got a response. Before I start
using crypto (e.g. blowfish) to encrypt my connection strings in web.config
I would like to know that it is necessary. I feel that it should not be
necessary.

I have an ASP.NET app running under IIS6 on a Windows 2003 Server in a DMZ
within our network. Obviously, this machine is not a member of any of our
domains. My app needs to talk to an SQL Server machine that not in the DMZ
and is a member of one of our domains. So, I have to cross not only a domain
boundary but also a firewall to get from the client to the server.

Is this possible using a trusted database connection?

Thank you for any and all ideas.

Dave
