is there a way to fix your windows 7 professional guest host os ipaddress so it does not change every time you startup? I am currently using NAT for networking and would like to remain using this networking method if possible. In older versions of windows this never used to be a problem in vmware so I am wondering if I am missing a setting in windows 7 professional or in vmware.

thank you for your help, chris

This question came from our site for professional and enthusiast programmers.

I'm on VMWare Workstation 6.5.1 and the IP of a Windows 7 prof. guest stays the same after restarts. I'd recommend to check DHCP lease duration in Virtual Network Editor for the NAT virtual host adapter (usually VMNet8). – Andreas Schuldhaus Dec 13 '10 at 18:06
this is a great idea, I am giving that a try now, I expanded the setting to 864000 with a max of 900000 – chrishough Dec 14 '10 at 15:52

I had a similar problem with an Ubuntu guest and couldn't change to a static IP, and fixed using the following:

You can allocate a static lease for behind NAT by adding it here (Win 7, VMWare Player 5):-

C:\Documents and Settings\All Users\Application Data\VMware\vmnetdhcp.conf

host UbuntuVM {
    hardware ethernet 00:0c:29:b7:86:ab;
  • you add it before the final #end
  • you need to change the example 192.168.216 above to your subnet
  • maybe allocate outside of the DHCP pool. I believe this is 123-254 so chose 99
  • you need to edit the security on the file to get permission to save it.
  • stop the vm before and restart the vmware dhcp service after you've saved the change
