I was trying to install BBIS on my local machine and when it go to the CMS Application User part I selected the normal default of Network Service User. However when I tried to hit next I was prompted with the following error message.
To get around this I simply connected to the Blackbaud vpn and tried again and it worked. Not really sure as to why this happened, however it’s always these little things that keep us stuck for hours. So if you get this, then connect to your domain and give it a go!
