I try mapping to the root drives (i.e. C$ or D$) with IP and server name of a new virtual machine running server 2012 R2. This is the first 2012 server in my OU. I keep getting "Windows cannot access 192.X.X.X". Server is joined to a domain. I can rdp using server name and IP. I can ping ip and server name. Did a flush and register dns, rebooted etc.. Is there some firewall setting or network sharing setting i'm missing ?
