While trying to configure a new DHCP scope in Windows Server 2016 I noticed that there is no DHCP Option 119 available. But adding it on your own just takes a few simple steps.
Logon to your DHCP server, open the DHCP Console. Right click IPv4 and select “Set Predefined Options…”.
In the “Predefined Options and Values” dialog select “Add…”. In the “Option Type” dialog add the following:
Name: Domain Search List
Data type: Byte, Array checked
Code: 119
Description Domain Suffix Search Order
After applying the settings you should see the option 119 in the server and scope options:
I don’t think a “Byte” data type will work here. I think you need it to be a “String” data type.
What do you mean by “I don’t think”? Did you try it? Did you test it? Every source I found states that this field uses a byte array.
How would you enter a domain name as a byte?
