I found out something the hard way and that is that you cannot run SharePoint Foundation 2013 on a domain controller. I should have researched it more. I am getting rid of our Windows Server 2003 domain controller and I installed a new Windows Server 2012R2 server to take over that role. I installed the OS and then set up SharePoint and it was working great. I copied all of my documents and folders to it and got it working like a champ. Luckily, I kept the SharePoint 2.0 server running on the old server while I was transitioning other things to the new server. I made the 2012 Server a domain controller and SharePoint never worked again.
Now, I have a dilemma. I don't want to keep a Windows Server 2003 around just to keep our SharePoint server running for internal use. I also do not want to spin up another VM with Windows Server 2012 as a member server because I don't want to spend the money on a license JUST to be a SharePoint server.
I really didn't expect this. Things were going so well that I figured I'd be hit in the face with the Microsoft 2x4 at some point. It happened.
Any advice? We really do depend on SharePoint a lot to keep a lot of company files available in PDF form, like manuals, policies, etc. It was so easy!
