This is just getting weirder.
When I go to connect I either name the instance or use (local). Then under options it is possible to click the drop down for databases. i.e I will select from a list. So hit the drop down and select browse server. This then appears to go get the info and display a window showing no databases (which is correct as there are no SSAS catalogs at the moment).
So it seems to allow browsing the instance for SSAS databases but still wont allow the connection?
Still gives unable to establish server mode. Could this be a firewall issue or is there something simple I have missed?
