Unfortunately, it appears that the source DNN download has neither "doc" or a "readme". If everything is so clear, why are the majority of the posts about the sme 3-4 issues. And , as best I can tell many of the posts are from experienced IT professionals.
BTW, I've installed several SQL Server systems and more than a few IIS websites. My major complaint is that there is no visible doc about the 3-5 changes that must be made to install, much less the "Oh by the way" "rename this", "download that", and "copy this". Specific examples: web.config, SiteUrls.config, template..., etc.
And I find it incredulous that one has to devine which standard logon accounts have to have their permissions altered. The end result of that, is that users end up giving full authority to any number of accounts and directories just to get things to work.
I also suggest that any system/application which when a problem is posed gets the answer "just wipe and re-install" is inherently poorly packaged/supported.
And getting back to my problem, I'm currently stuck on the standard "could not connect to database" problem. 4th iteration, third wipe/install.
