PowerShell script to set DHCP policies

Needs to work on Server 2012 and 2016

I am working on a PowerShell script that will
1) Configure vendor classes in DHCP - Working
2) Create policies based on these classes - Working
3) Set specific options (66 and 67) for each policy - Not working

The complete script is

Add-WindowsFeature -Name DHCP –IncludeManagementTools
Import-Module DhcpServer

$Server	= Read-Host -Prompt 'Enter the DHCP server name'
$Scope	= Read-Host -Prompt 'Enter the project network address (10.222.xxx.0)'
$WDSvr	= Read-Host -Prompt 'Enter the IP of the server hosting Deployment Shares'

$VendorClassUEFIx64 = @{
	Name = "PXEClient UEFI (x64)"
	Description = "PXEClient UEFI (x64)"
	Type = "Vendor"
	Data = "PXEClient:Arch:00007"
	}
$VendorClassUEFIx86 = @{
	Name = "PXEClient UEFI (x86)"
	Description = "PXEClient UEFI (x86)"
	Type = "Vendor"
	Data = "PXEClient:Arch:00006"
	}
$VendorClassBIOS = @{
	Name = "PXEClient BIOS (x86 & x64)"
	Description = "PXEClient BIOS (x86 & x64)"
	Type = "Vendor"
	Data = "PXEClient:Arch:00000"
	}
	
Add-DhcpServerv4Class @VendorClassUEFIx64 -ComputerName $Server
Add-DhcpServerv4Class @VendorClassUEFIx86 -ComputerName $Server
Add-DhcpServerv4Class @VendorClassBIOS -ComputerName $Server

Add-DhcpServerv4Policy -Name "PXEClient UEFI (x64)" -ScopeId $Scope -Condition OR -VendorClass EQ,"PXEClient UEFI (x64)*"
Add-DhcpServerv4Policy -Name "PXEClient UEFI (x86)" -ScopeId $Scope -Condition OR -VendorClass EQ,"PXEClient UEFI (x86)*"
Add-DhcpServerv4Policy -Name "PXEClient BIOS" -ScopeId $Scope -Condition OR -VendorClass EQ,"PXEClient BIOS (x86 & x64)*"

Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient BIOS" -OptionId 66 -Value $WDSvr
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient BIOS" -OptionId 67 -Value "boot\x86\wdsnbp.com"
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient UEFI (x64)*" -OptionId 66 -Value $WDSvr
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient UEFI (x64)*" -OptionId 67 -Value "boot\x64\wdsmgfw.efi"
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient UEFI (x86)*" -OptionId 66 -Value $WDSvr
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient UEFI (x86)*" -OptionId 67 -Value "boot\x86\wdsmgfw.efi"

This is the section that is not working, I have tried multiple ways of doing this and I know the script code is wrong at the moment

Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient BIOS" -OptionId 66 -Value $WDSvr
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient BIOS" -OptionId 67 -Value "boot\x86\wdsnbp.com"
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient UEFI (x64)*" -OptionId 66 -Value $WDSvr
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient UEFI (x64)*" -OptionId 67 -Value "boot\x64\wdsmgfw.efi"
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient UEFI (x86)*" -OptionId 66 -Value $WDSvr
Set-DhcpServerv4OptionValue -ComputerName $Server -ScopeId $Scope -DhcpServerv4Policy "PXEClient UEFI (x86)*" -OptionId 67 -Value "boot\x86\wdsmgfw.efi"

Hello David,

You may not work with Windows anymore but you got this right... worked perfectly

Replacement code for the last section is

Set-DhcpServerv4OptionValue -OptionId 66 -Value $WDSvr -ComputerName $Server -ScopeId $Scope -PolicyName "PXEClient BIOS"
Set-DhcpServerv4OptionValue -OptionId 67 -Value "boot\x86\wdsnbp.com" -ComputerName $Server -ScopeId $Scope -PolicyName "PXEClient BIOS" 
Set-DhcpServerv4OptionValue -OptionId 66 -Value $WDSvr -ComputerName $Server -ScopeId $Scope -PolicyName "PXEClient UEFI (x64)"
Set-DhcpServerv4OptionValue -OptionId 67 -Value "boot\x64\wdsmgfw.efi" -ComputerName $Server -ScopeId $Scope -PolicyName "PXEClient UEFI (x64)"
Set-DhcpServerv4OptionValue -OptionId 66 -Value $WDSvr -ComputerName $Server -ScopeId $Scope -PolicyName "PXEClient UEFI (x86)"
Set-DhcpServerv4OptionValue -OptionId 67 -Value "boot\x86\wdsmgfw.efi" -ComputerName $Server -ScopeId $Scope -PolicyName "PXEClient UEFI (x86)"

Glad I could help :)

I believe your original would have worked if you used the correct parameter name, -PolicyName instead of -DhcpServerv4Policy.
Position should never matter with named parameters. In PowerShell position of arguments only matters when you don't supply the parameter name (and not all parameters can be used without a name).

Hello footech,

Yes it works if I replace DHCPServerv4Policy with PolicyName and leave it in the original order.
