Every now and then, you may have notice the network connection for a Virtual Machine guest running on VMWare Server has stopped working. The guest VM could be running any version of Windows or Linux distribution and restarting the Virtual Machine does not fix the problem. If this happens to you, a possible work around to get the Network re-connected can be fixed by restarting the VMWare Server NAT service.
Several ways exist to restart the NAT service when running VMWare Server either on a Windows or Linus host. The easiest way is from the VmWare Server Console.
To re-start the NAT service, connect to the Console and select Host \ Virtual Network Settings… from the menu.
Select the NAT tab, and at the bottom click on the Restart button.
Then click on the Apply button, to restart VNWare Server NAT service. After the service has restarted, the Service request field will be blank and the Service status field will display Started.
Another method to restart the service, is from the command prompt on Windows by running the following command (NOTE: must include quotes):
net stop "VMware NAT Service"
then to restart the service:
net start "VMware NAT Service"
On Linux, open a Terminal window or session, and run the following command (depending on the distribution, this command may not work):
