1. Edit vmnetdhcp.conf at %ProgramData%\VMware\vmnetdhcp.conf

    The following is a sample which was reconfigured the DHCP subnet from 192.168.227.0/24 to 192.168.91.0/24.

    #
    # Configuration file for VMware port of ISC 2.0 release running on
    # Windows.
    #
    # This file is generated by the VMware installation procedure; it
    # is edited each time you add or delete a VMware host-only network
    # adapter.
    #
    # We set domain-name-servers to make some clients happy
    # (dhclient as configued in SuSE, TurboLinux, etc.).
    # We also supply a domain name to make pump (Red Hat 6.x) happy.
    #
    allow unknown-clients;
    default-lease-time 1800;                # default is 30 minutes
    max-lease-time 7200;                    # default is 2 hours
    
    # Virtual ethernet segment 1
    # Added at 03/06/23 10:26:32
    subnet 192.168.211.0 netmask 255.255.255.0 {
    range 192.168.211.128 192.168.211.254;            # default allows up to 125 VM's
    option broadcast-address 192.168.211.255;
    option domain-name-servers 192.168.211.1;
    option domain-name "localdomain";
    default-lease-time 1800;
    max-lease-time 7200;
    }
    host VMnet1 {
        hardware ethernet 00:50:56:C0:00:01;
        fixed-address 192.168.211.1;
        option domain-name-servers 0.0.0.0;
        option domain-name "";
    }
    # End
    
    # Virtual ethernet segment 8
    # Added at 03/06/23 10:26:32
    subnet 192.168.91.0 netmask 255.255.255.0 {
    range 192.168.91.128 192.168.91.254;            # default allows up to 125 VM's
    option broadcast-address 192.168.91.255;
    option domain-name-servers 192.168.91.2;
    option domain-name "localdomain";
    option netbios-name-servers 192.168.91.2;
    option routers 192.168.91.2;
    default-lease-time 1800;
    max-lease-time 7200;
    }
    host VMnet8 {
        hardware ethernet 00:50:56:C0:00:08;
        fixed-address 192.168.91.1;
        option domain-name-servers 0.0.0.0;
        option domain-name "";
        option routers 0.0.0.0;
    }
    # End
  2. Edit vmnetnat.conf at %ProgramData%\VMware\vmnetnat.conf

    # Windows NAT configuration file
    
    [host]
    
    # NAT gateway address
    ip = 192.168.91.2/24
    hostMAC = 00:50:56:C0:00:08
    
    # enable configuration; disabled by default for security reasons
    #configport = 33445
    
    # VMnet device if not specified on command line
    device = vmnet8
    ...
  3. Edit startup parametes of VMware DHCP Service at HKLM\System\CurrentControlSet\services\VMnetDHCP\Parameters\VirtualEthernetSegments\8\HostIpAddress.

    Please note that address has reverse HEX notation. e.g. [1]

    192.168.1.1 is reversed to 1.1.168.192 and key value is 0101A8C0

    According to the above sample, we should update this value to 15ba8c0, which is 192.168.91.1.

  4. Now, we need to restart the both the VMware DHCP Service and VMware NAT Service using Windows Services Manager.
