Network between 2 VMs not working - same config

Problem:

I have been using two VMs for my CRM Environment, VM1 has CRM and VM2 has domain controller, but VM1 cannot see VM2 despite having the same network config, same subment mask, ips are in the same range.

What I had to do:

VM1 was using NAT on Network Adapter
VM2 was using Bridged on Network Adapter

Solution:

Make sure both VMs are using the same config on network adapter:

I used Host Only on both network adapters. It worked
