I did a bunch of searches on here with similar issues, but to no avail. The issue I am having is we have our company AD Domain name the same as our external website running on a Windows Server 2012. This is a new AD setup for our company, and the reason we decided to keep the name the same is because we will be implementing single sign on with Office 365 in the future. When our internal employees access our company website it will go to the website like normal, but it strips out all of the headers of the website. All the content is up to date, and no links are broken, just images and structures are all stripped out. I've verified all the entries and everything looks normal. DNS flushing and registering doesn't work. I've never encountered this issue before, so if anyone has any ideas that would be great. Let me know what information you need. Thanks!!
