Installing web screen on another server

Hi all,

I have 3 servers:

A - 1 DB  Server

B - 1 Sage 300 Application server (using Sage 300 2021)

C - 1 Sage 300 web screen server (using Sage 300 2021)

Installing A and B is okay. I have a bit of problem installing C. I am following guide from https://help.sage300.com/en-us/2021/web/Content/Installation/InstallingWebScreens.htm

There is no mention of where the installation folder & shared data paths supposed to point. is it the installation folder & shared data folder from server B, or the installation folder & shared data folder of server C?

Thank you.
