After each numbered step, check whether your virtual machine has an Internet connection. There is no need to proceed with further steps once the issue is resolved.

To troubleshoot your network and Internet connection:

1. Ensure that your Host machine has a working network connection.
2. Confirm that your virtual machine's firewall is not blocking the Internet access. For information on turning off your firewall, see:
   • Windows XP: Microsoft article Turn Windows Firewall on or off
   • Windows Vista: Microsoft article Turn Windows Firewall on or off
   • Windows 7: Microsoft article Turn Windows Firewall on or off
   • Windows 10: Microsoft article Turn Windows Firewall on or off
3. Confirm that your virtual machine's anti-virus program is not blocking the Internet access. Consult the Help menu of the anti-virus program or see the manufacturer's documentation for instructions on configuring it correctly.
    
4. Run an anti-virus scan on your virtual machine to make sure there are no viruses or other malware interfering with your Internet connection.
    
5. Ensure that the network adapter is enabled. Follow the steps in the Microsoft article relevant to your version of Windows:​​
6. Change your adapter from NAT to Bridged, or vice-versa. If one selection works and the other does not, then the problem is with your network and not with Workstation or your virtual machine. For more information, see Understanding networking types in hosted products (1006480) .
7. Shut down the virtual machine, then restart your Host Machine.
    
8. After your Host machine reboots, reopen Workstation.
    
9. Download and reinstall VMware Workstation. This ensures that you have the most recent version, and that any missing or corrupted virtual network settings are replaced/repaired.
    
10. Confirm that Workstation services are working properly.
     
11. Uninstall and reinstall VMware Tools. For more information, see General VMware Tools installation instructions (1014294) .
12. Make sure that your network adapter is connected to the virtual machine by removing and re-adding it:
    • Shut down your virtual machine.
    • In Workstation, go to VM > Settings > Network Adapter.
    • Ensure that the network adapter is connected (that is, the Connected and Connect at power on options are selected).
    • Ensure that the network adapter is configured for NAT or Bridged, and not Host Only. Make a note of your setting.
    • Click on Remove.
    • From the Settings pane, select Add > Network Adapter to re-add your network adapter.
    • Verify that your new network adapter settings match your old settings.
    • Restart your Host machine.
    • Power on your virtual machine.
       
13. Update the Windows network adapter in Device Manager:
    • Start the virtual machine.
    • Click Start, right-click My Computer, and click Manage.
    • Select Device Manager from the left pane.
    • Click the arrow to expand the Network Adapters section.
    • Right-click your Ethernet Controller in that list (name may vary) and click Update Driver Software.
      • Select Search automatically for updated driver software. If the driver is not automatically detected:
        • Repeat the above step and select Browse my computer for driver software.
        • Select Let me pick from a list of device drivers on my computer.
          • For Windows XP, select VMware Accelerated AMD PCNet Adapter.
          • For Windows Vista and 7, select Intel Pro/1000 MT Network Connection.
      • Click Close.
      • Restart Windows.
         
14. Uninstall and reinstall all network adapters in the Device Manager:
    • Start the virtual machine.
    • Click Start, right-click My Computer, then click Manage.
    • Select Device Manager from the left pane.
    • Click the arrow to expand the Network Adapters section.
    • Right-click the Intel(R) PRO/1000 MT Network Connection (in Windows Vista and 7) or VMware Accelerated AMD PCNet Adapter (in Windows XP) device and select Uninstall.
    • In the menu bar, click Action > Scan for hardware changes.
    • Restart Windows.
       
15. Reset TCP/IP and Winsock settings to default:
    • To reset TCP/IP, follow the resolution steps in the Microsoft Knowledge Base article 299357.
    • To reset Winsock settings, follow the resolution steps in the Microsoft Knowledge Base article 811259.

• Collect diagnostic information. For more information, see Collecting diagnostic information for VMware products (1008524).
• File a support request with VMware Support. For more information, see Filing a Support Request in Customer Connect (2006985) .
