I am in the position of trying to set up a server system for my company using some provided instructions. I am not an IT professional, but am the only option available at the moment. So, I apologise in advance for my lack of knowledge - I'm very much trying to learn as I go. Anyway...
I have installed and configured ESXi 5.5 to run on a pair of host servers. After configuring the network and storage, my first task is to create a VM for Active Directory and DNS Server roles.
I have set up a VM and installed Windows Server 2008 Std (and updated VMware Tools). After entering the IPv4 details to the Network Adapters, I attempted to ping the IP addresses of other hosts on the subnet. All responses return host is unreachable. No roles or features have been added or configured at this point. I am able to ping the VM's own IP addresses.
Trying to ping the VM from another host on the subnet results in the same outcome - host unreachable.
I have disable the Windows firewalls and confirmed their status using netsh, just in case they were causing a problem - no effect.
I have disabled IPv6 at the Network Adapters.
Incidentally, I have installed other VMs on to the server to test (Win 7, Win Server 2012), using the same network settings as for the problem VM, I have no issues getting them to communicate with other hosts. Unfortunately, Win Server 2012 isn't compatible with elements of the version of VMware I have, so I have to find a way of getting Win Server 2008 up and running.
I'd be very grateful for any advice at this point.
