I have gone through setting up DNN (I've got my handy copy of Professional DotNetNuke 4 (from Wrox) and also read a couple of articles about configuring DNN on Windows Vista.  It's working fine on my Cassini server with VS2008 but when I publish to IIS now I get a "file not found" error.  it's frustrating because I've configured IIS to look for "default.aspx" and I've confirmed there IS a "default.aspx" in the root directory of my site, but nevertheless I'm getting that error.

What have I forgotten to check?  Once my site worked in Cassini, I published the site from VS2008 to the IIS server (using File System, since it's local to my LAN), but I can get nowhere once it's published.  What am I doing wrong?

This is quite frustrating.

I did find that I needed to make the change in the database.

This is a REAL newb question, but do I have to install DNN on the IIS server?  I mean, I installed it to my Visual Studio, then created a new DNN project, then published that entire project to my IIS directory.  Is that sufficient, or do I have to do something else?  I'm sure this is a dumb question, but I've been staring at this for 24 hours now, and I'm afraid that my years of ISP experience is making me presume/assume things that I should not presume/assume.
