Here are the steps I take to deploy DNN (I have several hundered installations under my belt):

1. Download the INSTALL version of DNN (not the source, vs integrated, or other version)
2. Unzip it to the folder you want your site in
3. Set the right permissions on the folder
   1. Right Click the folder
   2. Select Properties
   3. Select the Security Tab
   4. Set the following permissions
      1. Administrators: Full Control
      2. System: Full Control
      3. Network Services: Full Control
      4. Users: Read & Execut
      5. ASPNet: Full Control (if available)
   5. Click Ok
   6. if asked select to replace permissions on all child items
4. Open IIS and Create a Website/Virtual Dir that points to your folder
5. Open SQL Manager
6. Create a Database
7. Browse the DNN Site (DO NOT MAKE CHANGES TO THE WEB.CONFIG YOURSELF)
8. Walk through the Wizard that will configure your site

Let me know if you have any trouble.
