Description
How to manually update the domain name for a computer which was migrated using Resource Updating Manager (RUM) in the AD LDS database -
Cause
If a computer was migrated to the target domain using RUM, then this same computer is manually removed from the target domain and rejoined to the source domain outside of RUM, then it will still show the computer as being joined to the target domain within the RUM console. Even if the computer is removed from the RUM collection and re-added, it will not update the domain. In this case, the domain can be updated by manually editing the aelita-amm-DomainName attribute for the computer within the AD LDS database. -
