I am installing ArcGIS Enterprise 10.6.1 on a completely new virtual server, and plan to migrate existing services and data from a 10.3 Server and SDE SQL database over the next few months. (I'm going with Option 2 from the "Migrating standalone ArcGIS Server to ArcGIS Enterprise" whitepaper.)
IT set me up with a Local Admin account and password to use while installing the software on the server. The installation seemed to have gone well (with the help of Esri Tech Support) but I am getting 'Unauthorized Access' errors when I try to log into the ArcGIS Server Manager site under any windows login other than the one used to install the server software.
Is that how it is supposed to work? I can get to my 10.3 server manager site on any computer, as long as I supply the proper username and password to get into Server Manager. Have a missed a setting or step when installed ArcGIS Server Manager 10.6?
