+
+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](https://technet.microsoft.com/en-us/library/cc774834%28v=ws.10%29.aspx?f=255&MSPPError=-2147217396) 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:
+```powershell
+# 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:
+```powershell
+# 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!
+
+```powershell
+Set-DnsServerPrimaryZone -DynamicUpdate Secure
+```
