Eric,

I recommend you search the forums - use the search on the menu bar on DotNetNuke Site as this will seach the forums using Google search.  Also check out Mitchel Seller's site for help - for example this blog post. 

Also, there may be specifics about the host of the remote web server that you need to follow.  I would contact the host provider to ensure you follow there instructions.  If you just want to test DotNetNuke on the site, many providers will create a site for you.

Lastly, the more specific the questions, the better the help can be.  So please provide as much detail as possible.  For example, what version of DNN,  what specific issue you encountered (error messages)

Hope this helps
Paul.
