What VMware product and version?
What Host OS product and version?
What Guest OS product and version?
How is the Guest's Virtual Network Adapter configured in its Settings? NAT, Host-Only or Bridged? (Based on the IP Addresses I assume it's not Bridged)
If you were to run two separately created VM's not one copied to the other and just using defaults and no editing anything and on the same Subnet are they able to ping each other?
