If the CRM reports get removed from the SQL Reporting Services Server they can be republished at the CRM server by using a command-line program. Navigate to the CRM installation folder, usually C:\Program Files\Microsoft Dynamics CRM and then to Tools. Within this folder run the following command:
C:\Program Files\Microsoft Dynamics CRM\Tools> PublishReports "organizationname"
where organization name is the internal name of the CRM organization (as found in Deployment Manager).
