Powershell – Set Remote Computer To DHCP Enabled Without Using WinRM

It doesn't know what device to query. Thus it broadcasts its request to the entire subnet. The DHCP server is listening for a certain type of communication and when it hears that specific broadcast it begins the DHCP conversation with the device that broadcasted its request. Take a look at the DORA process for more information.

DORA stands for:

• D iscovery
• O ffer
• R equest
• A cknowledgement

As for the gateway, it can come into play only if it explicitly forwards DHCP traffic to another subnet. That feature is usually called DHCP Relay. Otherwise the gateway ignores the broadcast DHCP message just like it ignores every other broadcast message.

As for redundant DHCP servers, you'll want to keep them both on the same subnet and probably use the 80/20 rule. You can set up failover if you're using CentOS as your DHCP server.

Lets say you have an interface called "Local Area Connection 1" that you want DHCP to set WINS addresses for:

netsh interface ip set wins name="Local Area Connection 1" source=dhcp

Now, you might want "Local Area Connection 2" to have a static WINS source:

netsh interface ip set wins name="Local Area Connection 2" source=static addr=10.0.1.11
