Change VMWare Player 3.X IP Address

To change the IP address range or the DHCP addresses when using Windows as the host OS use the program called vmnetcfg.exe.

This program is included in the installer but isn’t installed. To get to it:

1. Run the installer with /e option. For example:

VMware-player-3.0.0-197124.exe /e vm

All contents will be extracted to “vm” folder.

2. Open “network.cab” and copy vmnetcfg.exe to your installation folder,
typically “C:\Program Files\VMware\VMware Player\”.

Now you can use vmnetcfg.
