I setup a new WSUS server using Server 2012. I configured WSUS and IIS (utilizing SSL as well). I am doing some testing before we implement WSUS and I'm having a strange issue. First of all, we have several environments (dev, test, prod) and domains on our network. My laptop is on a different domain than the WSUS server, but I can successfully communicate with WSUS through my web browser. I launch IE, type https://wsusserver.domain.local (I'm using generic terms for the forum). I get a screen that says my certificate is not trusted, or something. That's another story, but the point is that my browser connects to the WSUS server. However, one one of our VMs in the dev environment which is on a different domain, I follow the same procedure and get "The page can't be displayed." I've rebooted the VM, refreshed group policy, flushed DNS cache, rebooted the server, etc. I doubt that the WSUS and IIS configuration is wrong because my laptop can connect to it. Any ideas?
Update: I can connect to the WSUS server now via IP address and IIS site name. For example, https://192.168.3.45/WSUS_Administration
