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
|
|
```
