I have a VM that is unreachable every new day, because it got a new IP in a other subnet i believe (other subnet mask ie 255.255.0.0 instead of 255.255.255.0). What could be the cause of this. I'm running Hyper-V on Windows Server 2008 R2 SP1.
Things complicating this setup is that the router acts as a DNS and a DHCP and the server also acts as a DNS. All the workstations and servers are configured to choose the Server (192.168.1.6) as the primary DNS.
What could be the reason for this problem?
- 192.168.1.1 is the router
- 192.168.1.6 is the server
- 192.168.1.78 is the hyper-v host
Below: The IP settings for the Hyper-V host and the VMs share the same except for the IP address.
I wanted to post the question on serverfault but don't have the points for the picture.
