Yes, that’s correct, if you’ve decided that you’re going to build out your SharePoint environment in an Internet disconnected environment, or on an island as I prefer to call it… be sure that your environment isn’t locked down such that you can’t even run the prereqinstaller to configure your server application roles.
So you say that you are getting an error and you’re in an Internet disconnected environment? First, check to see if you forgot to install a component, or if you’re crafty and strung together your prereqinstaller with a script to install everything for you check to make sure there’s not a typo.
Not that? Open the log file and check to see if you see a line in there stating that Windows Script Host is disabled. If it is, not too hard to fix… just wander over to your friendly TechNet article about Windows Script Host at:
The value for “Enabled” in HKEY_LOCAL_MACHINESoftwareMicrosoftWindows Script HostSettingsEnabled is probably set to “0”, flip it to “1” to enable WSH, run the PrereqInstaller which has scripts for configuration and then flip it back to “0”.
Note that Windows Script Host is not required for installing the actual SharePoint bits, just to run the scripts to setup your server roles properly.
Enjoy your island environment 🙂
