I haven't had time to install anything else on this VM, I'll have to think about other roles or features that I might want to try to see if additional services will cause additional problems. WDS might be a good one since it opens up a few different services, but really only good for Win10 stuff these days.
I could install the Shoutcast server (as a service), but not sure if it plays nice with AD DS, would be simple enough to point a stream at it and play the audio locally once it is set up.
Do you think Zabbix agent would trigger it? I could get that going pretty quick and use it to test things with Zabbix while doing it.
