There are a couple of posts here dating back to 2007 asking how to change the port from 80 to something else. The response talks about editing a file that does not appear to exist on my 2014 R2 GMS setup (which runs on a XEN VM).

Is there a way to change the port number by running the GMS installation all over again, or can some other file be edited? Or should I blow the VM away and create a new one for my little network.

[By way of explanation, GroupWise is running on another VM, and in order to enable GW Web Access on that VM I need to enable / forward either http (80) or https (443) to that VM. Right now either GMS works, or GW Webaccess works depending on which VM I forward port 80 to in the router].

Thanks for any tips
