Hey Ali, Yes it is a Windows Server 2012 R2.
"HomeServer.DreamScape.local", HomeServer is the name of the machine, DreamScape the name of the domain. I'm not too familiar with that concept tbh, I had to define one on installing the OS and so far it didn't interfere with much of my network usage. Concerning the the firewall, I only defined the Port for TCP. But as I said, with the same settings the RC4 binary of WIAB is working fine, I don't have to use any domain for reaching the webpage, just the ip or the internet domain + :9898 at the ned and its working. Best regards, Ronny
