Hi,
We have some virtual machines in a virtual network, one of them is acting as a DC.
When we deploy a new virtual machine, we set up the DNS addresses.
The problem is that sometimes the virtual machines are restarted (I guess for maintenance issues) and the DNS configuration is lost, it's set as "Obtain DNS server address automatically" instead of our preferred DNS address.
When this happens the virtual machine is not logged in the domain and unreachable by the domain users.
