So, in my virtual homelabbing, I decided I was going to get a Windows based network set up with more or less only PowerShell. In these efforts, I discovered a pretty poor pile of documentation (such as this insanity where they tell you to create credentials with netsh, restart the service, then delete the credentials and restart again [optional step: wonder why it doesn't work]).

####Here's how I set it up: #####Create AD account:

# Get username and password for the new account (remember to include your domain!)
$cred = Get-Credential

# Create the user (it needs no special permissions)
New-ADUser -Enabled $true -SamAccountName $cred.UserName -AccountPassword $cred.Password

#####Make the DHCP server use it:

# Set the credentials for the DHCP server
Set-DhcpServerDnsCredential $cred

# Restart the DHCP Server
Restart-Service DhcpServer

You're set!

###Bonus:

Also remember to set the DNS server to only allow secure updates!

Set-DnsServerPrimaryZone -DynamicUpdate Secure
