Hello,
I have installed Portal for ArcGIS 10.9.1 (wadesappgis001a) and ArcGIS Server 10.9.1 (wadesappgis002a) on two separated machines. The base installation was successful, but when I would done the federation, it will not work. Research with the IT people, it seems that the used WebAdaptors IP address point to a non desired IP.
Below the situation: on machine wadesappgis002a I have following situation, machine point to two different IP address.

When I install the WebAdaptor, I receive following situation:

How is it possible to force the WebAdaptor from ArcGIS Server to use IP address from machine to IP=10.36.85.14.
I had the same problem with the Portal WebAdaptor, to change the IP Adress, I used the the edit mode.

Is there somewhere a same edit mode for ArcGIS Server or another solution to resolve this?
