Invoke-Command Elevation Issue - powershell

Question

I'm trying to run Invoke-Command with an answer file to the user credentials but I can't seem to get it to finish running. I'm using a local administrator account so nothing on the domain. Here is what I have and the error:
$Username = "$Env:Computername\admin"
$Pass = ConvertTo-SecureString "12345" -AsPlainText -Force
$User = New-Object Management.Automation.PSCredential($UserName, $Pass)
Invoke-Command -ComputerName $Env:Computername -Credential $User -ScriptBlock {
$Path = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System'
$Name = 'DontDisplayLastUserName'
Set-ItemProperty -path $Path -name $Name -value 0
}
And the error:
[computer] Connecting to remote server failed with the following error message : WinRM cannot process the request. The following error occured while using Kerberos authentication: There are curren
tly no logon servers available to service the logon request.
Any help is greatly appreciated.
Working Solution:
$Username = "$Env:Computername\admin"
$Pass = ConvertTo-SecureString "12345" -AsPlainText -Force
$User = New-Object Management.Automation.PSCredential($UserName, $Pass)
Invoke-Command -ComputerName localhost -Credential $User -ScriptBlock {
$Path = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System'
$Name = 'DontDisplayLastUserName'
Set-ItemProperty -path $Path -name $Name -value 0
}

Answer 1

I finally figured out the problem, hit me kind of randomly. The following line needed to be changed.
Before:
Invoke-Command -ComputerName $Env:Computername
After:
Invoke-Command -ComputerName localhost
Without localhost it was looking at it like a remote computer and not allowing it access.
