I am trying to install Lync server 2013 in my test VM Enviroment.
I have come across this problem when i am at this step like the attached. I have done all the prerequisites, and also builid topology.
I have read up some articles, that when Installing Lync 2013, it cannot be installed on Domain Controller.
If i am not mistaken Lync server 2010, has this issue also but can be resolve by some powershell or SQL commands.
Any body knows how to solve this issue without setting up another VM Server 2008 and make it as a member server, which i believe it's sure an solution.
eventually, to save cost, we might want to use only 1 server to add as FE server.
