Windows 2008 R2 Domain Controller using a Managed Service Account - Service not starting

Hi,

today I created a Managed Service Account using these lines:

New-ADServiceAccount -Name dc007vmt -enabled $true

Add-ADComputerServiceAccount -Identity dc007 -ServiceAccount dc007vmt

Install-ADServiceAccount -Identity dc007vmt

Then I changed the account in the services.msc console and confirmed all questions. - It looked fine:

Then I rebooted the computer and noticed that the service did not came up.

I tried to start the service but received this error:

Any suggestions?

Thanks in advance
