User credential permissions

Question

Added a ADDSForest using Powershell.
Trying to add a ADDSDomainController with Powershell but I get this error:
"Verification of user credential permissions failed."
There must have been something wrong with:
$Username = "Administrator"
$SecurePassword = ConvertTo-SecureString "$%PaSsWOrD" -Asplaintext -Force
$credentials = New-Object System.Management.Automation.PSCredential -arguments ($Username, $SecurePassword)
Import-Module ADDSDeployment
Install-ADDSDomainController `
-Credential $credentials `
because I had to enter my credentials manually as if I had "Get-Credentials".

Answer 1

Try this:
$UsernameUser = 'Administrator'
$PasswordUser = '$%PaSsWOrD'
$passUser = ConvertTo-SecureString -AsPlainText $PasswordUser -Force
$CredUser = New-Object System.Management.Automation.PSCredential -ArgumentList $UsernameUser,$passUser
It always work for me.
Of course, make sure that the credentials you enter are correct.
