Hello,
I am working on migrating our Intranet site from an old, neglected Windows 2003 server with Apache to a new server running Windows 2012 R2 and IIS 10. I have to use IIS on the new server because we are consolidating it with another web server we use internally which needs IIS.
The problem that is occurring is that whenever permalinks are on any non-default settings, the majority of pages give a 404 error. I have triple checked .htaccess and know that is not the issue. I went to update the permalinks multiple times as I read that can correct this, but this has not helped either. My .htaccess is writable so wordpress can auto-update it as necessary.
You might be thinking that I should just keep permalinks on default. However even with everything on default there are a select few custom pages which return a HTTP 500 error.
Are there any other steps I can take to get this to work properly? Thank you
