(2008 R2) AD RMS Installation Failure: ALTER DATABASE failed because a lock could not be placed on database

Question

First-time install on a SBS 2011 server, name replaced as <SERVER> for this post. I had created a separate IIS site rather than using the Default Web Site and I am guessing this might be a permission issue on the folder...
Installation failed with Event ID 110 and a repeating error that states, "<Error>: Attempt to configure Active Directory Rights Management Server failed. The provisioning process failed to create the Configuration database due to the following
error from Sql Server: System.Data.SqlClient.SqlException: ALTER DATABASE failed because a lock could not be placed on database 'DRMS_Config_adrms_<SERVER>_local_443'. Try again later. ALTER DATABASE statement failed. ALTER DATABASE failed because a
lock could not be placed on database ." Configuration as follows:
<Informational>: This server might need to be restarted after the installation completes.

Hi Ahmad, I have the same problem, I have a server windows server 2008 R2 standard. While
doing an Enterprise to Standard downgrade, I have removed enterprise edition of SQL Server 2008, rebooted and while installing standard edition, I get the below error saying "You SQL server 2008 installation completed with failures. Some or all identity
references could not be translated"
Bit of background. This server has another express instance of SQL Server 2008. I have
used local system account, network service as well as our general SQL service account, but I get the error towards the end of the installation and it fails saying “Some or all identity references could not be translated.”
I am installing a named instance with the same name as before but fails. I have tried
creating a new test instance that fails too. Any ideas? I have uninstalled SQL enterprise edition from
Add and Remore Programs/Programs and Features. I've also run the Windows Installer CleanUp Utility but no joy.
Cheers
