Look at the properties of your Virtual Machine (Open VMware -> Edit the Settings of the VM). Look at the network adapter. Is it set for NAT? or is it set to Bridged?
Assuming you have a router or server external to the Windows 7 host machine, try Bridged mode and see if that works.
If you are running in NAT mode, the VM is on a different subnet from the Host machine. Make sure the Host firewall allows traffic from the VM subnet range.
It seems like you have a DNS problem, and the solutions may be different depending on whether you use Bridged or NAT network mode. .... Thinkpads_User
