In this post - http://msmvps.com/blogs/richardsiddaway/archive/2011/09/23/powershell-3-and-dhcp-2-scopes.aspx - we created a new DHCP scope.

Now we need to set some options on the scope. One of the main options we need to set is the DNS server

We can see the available options using

Get-DhcpServerv4OptionDefinition -ComputerName server02

This displays a list of the available options – remember that we can add our own so this isn’t necessarily a static list

The options that are set for the test scope are

PS> Get-DhcpServerv4OptionValue -ComputerName server02 -ScopeId 192.168.100.0

OptionId   Name            Type       Value                VendorClass     UserClass       PolicyName
--------   ----            ----       -----                -----------     ---------       ----------
51         Lease           DWord      {86400}

The DNS server for this scope can be set like this

PS> Set-DhcpServerv4OptionValue -ComputerName server02 -ScopeId 192.168.100.0 `
-DnsServer 10.10.54.201

OptionId   Name            Type       Value                VendorClass     UserClass       PolicyName
--------   ----            ----       -----                -----------     ---------       ----------
6          DNS Servers     IPv4Add... {10.10.54.201}
