Why does my Windows 2008 server keep loosing its gateway IP?

I have come across this issue and it seems most common in virtual machines. The fix I found is:

  1. Logon to the server (using ILO or virtual console)
  2. NIC settings (and write down all settings)
  3. Open a CMD prompt with elevated permissions (“Run as Administrator”)
  4. Run the command:
    netsh int ip reset
  5. Reboot the server
  6. Logon again
  7. Set the correct NIC settings
  8. Reboot the server
