Error Opening InDesign File After Transferring from Server to Local Machine

I do not know why I am getting this message. I have never seen this before in all the years I've been using Adobe apps.

I had some files on my server. I copied them to a transfer drive. I then copied them to my production machine. I do not have my server mounted to my production machine. 

I open a InDesign file and this is what I get.

I am current on all apps and OS.

 TIA
