Very small business wants to provide shared RDS access to Office and an MSAccess application on Win2016 server. We are talking about a total of 5 users hitting the server, most likely at different times - but full concurrent logins could be a possibility.
The server is setup from Remote Desktop Services, and the Licensing is activated with 5 RDS CALs. The installed version of Office 2019 Professional is not going to work, as attempting to run the program during a RD session give the error "This copy of microsoft office cannot be used on a computer running terminal services".
In doing searches, I have seen some fixes that involve a registry change and group policy setting - but this server does even have a domain defined. Setting up AD seems overkill for such a small environment. Also, is an Office Open License even available for a quantity of 5?
