I believe this is because of our unfortunately-fractured domain setup.
A previous developer wrote a number of sites that only run in ASP/.Net and they all live on the host with the A record for pesgce.com — they are all eventually going to be shut down, but for now they have to live where they are (as pesgce.com/[i]stuff[/i]). Our current Web development lives on a Mac OS X Server, which is where PHPDocX is installed and where it will be used. All projects on that server live in subdomains of pesgce.com, so I logically assumed that the corporate version of this software would understand that, e.g., *.am.pesgce.com is within the domain pesgce.com… but I’m guessing that you validate on strict A record IP address matching.
I am at a loss for what to do here. I cannot move the A record for pesgce.com, as it would break existing software; but purchasing six or more “Pro” subdomain-tied versions of PHPDocX is prohibitively costly when the projects that use it will be within *.pesgce.com
