[<CommonParameters>]Description
The Set-DhcpServerv4OptionValue cmdlet sets an IPv4 option value at the server, scope, or reservation level. The definition for the option must already exist. This cmdlet fails if the option definition does not occur in the Dynamic Host Configuration Protocol (DHCP) server service.
If you specify only the ReservedIP parameter, the option values are set at the reservation level. If you specify only the ScopeId parameter, the option values are set at the scope level.
If you specify neither the ScopeId nor ReservedIP parameter, the option values are set at the server level. If you specify the VendorClass parameter, the option value is set for that vendor class.
If you specify the UserClass parameter, the option value is set for that user class.
If you specify the PolicyName parameter, the option values are set for that policy. The UserClass and PolicyName parameters cannot both be specified. The ScopeId and ReservedIP parameters cannot both be specified.
The PolicyName and ReservedIP parameters cannot both be specified.
The option values for policies can only be set for a DHCP server service that runs on Windows Server® 2012 and later versions of the Windows operating system. Setting user class options for a DHCP server service that runs on Windows Server 2012 and later versions of the Windows operating creates of a policy with the policy name set to the name of the user class. For a DHCP server service that runs on firstref_server_7 or earlier, only option values based on the user class can be set.
To set options based on legacy user classes, the UserClass parameter must be specified.
Examples
Example 1: Set server level option values
PS C:\> Set-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -DnsServer 192.168.1.2 -WinsServer 192.168.1.3 -DnsDomain "contoso.com" -Router 192.168.1.1 -Wpad "http://proxy.contoso.com/wpad.dat"This example sets the server level option values for DNS server, WINS server, DNS domain, router, and WPAD.

Example 5: Set service-wide option value for DNS server
PS C:\> Set-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -OptionId 6 -Value "192.168.1.1"This example sets the server-wide DHCPv4 option value for option ID 6, or DNS server.

Example 8: Set a vendor class specific option value
PS C:\> Set-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -VendorClass "MSUCClient" -OptionId 5 -Value "6874747073"This example sets the vendor class specific DHCPv4 option value for option ID 5 on the specified scope for the specified vendor class named MSUCClient.
Example 9: Set option value for DNS server for a policy
PS C:\> Set-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -PolicyName "PrinterPolicy" -OptionId 6 -Value "192.168.1.10"This example sets the DHCPv4 option value for option ID 6, or DNS server, on the specified scope for the specified policy.
Example 10: Set a user class specific option value for DNS server
PS C:\> Set-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -UserClass "LabComputer" -OptionId 6 -Value "192.168.1.10"This example sets the user class specific DHCPv4 option value for option ID 6, or DNS server, on the specified scope for the specified user class.
