If you come from the Dynamics NAV community you probably have seen the blog post from one of my favorite bloggers: Port Sharing with NAV2013. This blog describes in detail on how to set up port sharing to several NAV service tiers (NST).
So what is new then? If you run the 1VM/2VM script it will by default install a NST service with a local user account instead of using one of the system accounts. So if you follow Waldo´s instructions on how activate port sharing you will get an error like this:
The service MicrosoftDynamicsNavServer$DynamicsNAV80_Instance1 failed to start. This could be caused by a configuration error. Detailed error information:System.ServiceModel.CommunicationException: The service endpoint failed to listen on the URI ‘net.tcp://SERVERNAME:9001/DynamicsNAV80_Instance1/Service’ because access was denied. Verify that the current user is granted access in the appropriate allowAccounts section of SMSvcHost.exe.config. —> System.ComponentModel.Win32Exception: Access is denied
