Does the VM obtain an IP Address correcly via DHCP from the "NAT DHCP Server"?

Firewall enabled on host or VM?

If you set dhcp does it get an IP address just as a test?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
it looks like, Network Configuration has changed for the NATTed network to

192.168.254.x, from 192.168.183.139.

It's often easier to deal with DHCP for smaller networks, but yes, if you have staitcally allocated VMs to 192.168.183.x, change over to 192.168.254.x,.

You could check the VMware Network Configuration Editor?

and check what Subnet it's conmfigured to.

two options:-

1. change all your VMs.

or

2. change the IP Address range in the Network Editor, to 92.168.183.xxx.

Something, has reset or changed this IP Address range from the original.
