Are you meaning multiple instances of node-red on ONE Windows Server - each with a different port number?
Or 1 Node-RED on 1 Windows Server with a port different to the default 1880 port?
Either way, for Windows Server, I would recommend
- NPM Global is moved to somewhere common (e.g.
c:\programdata)- See here: Running on Windows : Node-RED
- separate directories for each node-red instance
- see this post: Node red multiple instances - #7 by Steve-Mcl
- use of NSSM with a service account for running node-red
