Hi!
Windows Server 2008
IIS 7
Arcgis Server 10.3.1
I have installed Arcgis server and then authorized it offline (the computer is connected to internet but somehow I couldn't)
I am trying to access for the first time the Manager but i get the error 404.
I checked the service and even if it showed "Started" this is what i see if i double click the service (I guess it's wierd, but...)

I have tried to enable the .ASP.NET 2.050727 as reported here 38370 - HTTP 404: "The page cannot be found" when trying to launch ArcGIS Server Manager (I know the version is not included in the the list but I wanted to give it a shot) but the asp.net is allowed.

I ve tried both with W Firewall on and off. Nothing changes.
Thanks.
