\u201cDisable VirtualBox DHCP for host-only network<\/strong>\u201d means:<\/p>\n\n\n\n

\n

Turn off the built-in DHCP server inside VirtualBox<\/strong>, so your Windows Server DHCP service<\/strong> becomes the only DHCP server giving IP addresses to the client VM.<\/p>\n\n\n\n

\"\"<\/figure>\n<\/blockquote>\n\n\n\n

Why this matters<\/h2>\n\n\n\n

In your DHCP lab, students are installing and configuring DHCP Server on Windows Server 2019<\/strong>.<\/p>\n\n\n\n

But VirtualBox host-only networks can also have their own DHCP server. If VirtualBox DHCP is enabled, then the client VM may get an IP address from VirtualBox<\/strong>, not from the Windows DHCP Server.<\/p>\n\n\n\n

That would make the lab confusing because students may think their Windows DHCP scope is working, but actually VirtualBox gave the IP.<\/p>\n\n\n\n

Simple example<\/h2>\n\n\n\n

You want this:<\/p>\n\n\n\n

Windows Server DHCP VM\n192.168.XX.10\ngives IP addresses to client\n<\/code><\/pre>\n\n\n\n
Not this:<\/p>\n\n\n\n
VirtualBox DHCP\ngives IP addresses to client\n<\/code><\/pre>\n\n\n\n
So we disable VirtualBox DHCP.<\/p>\n\n\n\n
What to disable<\/h2>\n\n\n\n
Disable only this:<\/p>\n\n\n\n
VirtualBox Host-Only Network DHCP Server\n<\/code><\/pre>\n\n\n\n
Do not<\/strong> disable the host-only adapter itself.<\/p>\n\n\n\n
The host-only adapter\/network should still exist so the VMs can communicate with each other.<\/p>\n\n\n\n
Steps in VirtualBox<\/h2>\n\n\n\n
In VirtualBox:<\/p>\n\n\n\n
    \n
  1. Open VirtualBox Manager<\/strong><\/li>\n\n\n\n
  2. Go to Tools<\/strong><\/li>\n\n\n\n
  3. Open Network<\/strong><\/li>\n\n\n\n
  4. Select the Host-only Network<\/strong><\/li>\n\n\n\n
  5. Go to the DHCP Server<\/strong> section\/tab<\/li>\n\n\n\n
  6. Uncheck or disable Enable Server<\/strong><\/li>\n\n\n\n
  7. Apply\/save<\/li>\n<\/ol>\n\n\n\n
    In some versions:<\/p>\n\n\n\n
    File \u2192 Tools \u2192 Network Manager \u2192 Host-only Networks \u2192 DHCP Server \u2192 Disable\n<\/code><\/pre>\n\n\n\n
    or:<\/p>\n\n\n\n
    File \u2192 Host Network Manager \u2192 select host-only adapter \u2192 uncheck DHCP Server\n<\/code><\/pre>\n\n\n\n
    After disabling it<\/h2>\n\n\n\n
    Your DHCP lab should use:<\/p>\n\n\n\n
    Machine<\/th>IP setting<\/th><\/tr><\/thead>
    DHCP Server VM<\/td>Static IP, example 192.168.XX.10<\/code><\/td><\/tr>
    Client VM<\/td>DHCP \/ automatic IP<\/td><\/tr>
    VirtualBox DHCP<\/td>Disabled<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    Then the client should get an address from your Windows DHCP scope, for example:<\/p>\n\n\n\n
    192.168.XX.100 to 192.168.XX.150\n<\/code><\/pre>\n\n\n\n
    Student-friendly wording<\/h2>\n\n\n\n
    \n
    Disable VirtualBox DHCP on the host-only network so that the Windows Server DHCP role is the only DHCP server in this lab. Keep the host-only network enabled, but turn off its built-in DHCP server. Otherwise, the client may receive an IP address from VirtualBox instead of from your Windows DHCP scope.<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"
