the links probably arent that much help to you, now that i know what is going on. They will however give you a nice overview of asp / coldfusion - which will be handy in your quest!
I personally dont run either asp or coldfusion so my experience is limited. I just go for the free unix / php solutions.
There could well be some problem though with using both, epsecially with if their are any shared configurations which relate to the database.
Can I ask why you are swaping from coldfusion to asp? Actually something that might be benefical for you todo, if you can, is setup your site with asp on another server (without coldfusion installed) and then if this works at least you know your asp scripts are working fine and then surely there is a problem with the combination of the two....
