My workstation was recently updated to Windows 10, and I'm suddenly unable to access my Portal for ArcGIS (10.4 AND 10.6 instances) from IE 11.
I can access through Chrome, however my issue is that trying to authorize ArcGIS Pro 2.1 with my Enterprise forces a login popup which is IE (and cannot be changed), and therefore fails.
While I'm not the administrator of my computer's security settings, I am the administrator of ArcGIS Enterprise. Is there anything I can change in my Enterprise to allow IE 11 / Windows 10 to connect? OR, what do I need to tell my friendly IT folks to change on my computer so I this issue goes away.
