I am attempting up upgrade from ArcGIS Server 10.4.1 to Enterprise 10.5 and I receive the following error when going through manager:
Upgrade step 2 of 2 : Failed. Cannot start machine as it does not participate in an cluster.
As far as I am aware this server is not part of a cluster so not sure why that is causing failure. There is no way to login and change settings, or even see what is going on. The only options it gives me is to upgrade.
Any help would be greatly appreciated. I'd hate to have to uninstall and start all over.
Thanks in advance.
