We are joining the Storage Spaces cluster to a Windows Domain. Join every cluster node to your domain and rename the nodes to match your IT standard naming scheme.
This is done in the standard Windows methodology via the Server Manager GUI. The PowerShell equivalent is provided below. This must be done on both nodes.
$UserName = "administrator"
$SecurePassword = "YourPassword" | ConvertTo-SecureString -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential -ArgumentList $UserName, $SecurePassword
Add-Computer -computername <nodename> -domainname <domain> -credential $credential –Restart
All nodes will have to be rebooted.
