The first thing to do: check that your network is running. Try ping the host system or any website from the guest OS console, say ping www.google.com .
If you get answers, try writing down the IP address of the host machine in the address bar of the browser on the guest machine (NOT localhost: P). You should see that any web service is running (Tip. Open your windows 7 console and enter ipconfig , then find the ethernet adapter matching VMWare and you will find the IP number of your host system).
If you didnโt get any response at all when you ping , then check VMWareโs network configuration for Bridged Connection โ at least the way it works for me.
Good luck
