I'm currently testing an ArcGIS Server (10.3) deployment. I've published a sample geodatabase and map as geodata and map services on the server. I've linked these services with our ArcGIS online account and created a web map and web app from them. My issue is this: I can view the data with attachments on the web app from the web browser on the server. If I view the same page on the web browser on other computers, I can't see the data. I have everything set in the server manager and on ArcGIS online to share with everyone(public). Is this an issue in the IIS manager on the Windows Server, or on the ArcGIS server itself? Currently our server is local to our network.
