SUMMARY
Event ID: 5051
Source: Application Center
Description: Could not set security descriptor
Event Type: Error
Could not set or change security descriptor (ACL) on the object
%Path% during synchronization session
%ReplicationID% and job
%ReplicationJobID%. Status is
%Status%%StatusMessage%.
Meaning: Could not set or change the security descriptor on the object.
Effect: If this is a cluster member, the ACEs for these resources on the target member will be replaced by "Administrator - Full Control". The rest of the cluster is not affected by this problem. If this is the cluster controller, the ACEs for these resources on the entire cluster will be replaced by "Administrator - Full Control".
Possible Causes and SolutionsWrong permissions: One probable cause of this is that the source server has an account on it for the resource that is not valid for the target server. To avoid this, use domain accounts for resources.
Account changed or missing: The AC*_ accounts have been changed or deleted. Application Center creates these accounts for performing tasks. If these accounts have been changed or deleted, see your support personnel.
