dSCorePropagationData attribute
dSCorePropagationData attribute
AD uses an internal background process called the Security Descriptor Propagator (usually abbreviated SDProp) to apply inherited permissions to child objects. In a very large environment, you might not see inherited permissions applied immediately. If you’ve ever noticed an attribute called dSCorePropagationData in AD and wondered what it does, this is the attribute that stores state information for SDProp.

dSCorePropagationData’ get’s updated once a ntSecurityDescriptor is updated by the Security Descriptor propagation demon (SDPROP) – that happens when security is changed on a object higher in the hierarchy and has to be propagated/inherited to subordinated objects. Note: This process is local and happens on each DC.
What are some common issues that can arise if the dSCorePropagationData attribute is modified manually?
Modifying the dSCorePropagationData attribute manually can cause replication issues and other problems in the domain. Here are some common issues that can arise if this attribute is modified manually:
Replication issues: The dSCorePropagationData attribute is used to track replication status between domain controllers. If this attribute is modified manually, it can cause replication issues and inconsistencies in the Active Directory database, which can result in data loss or corruption.
Authentication issues: The dSCorePropagationData attribute is used by the “lastLogonTimestamp” attribute, which is used to track the last time a user or computer account logged on to the domain. If the dSCorePropagationData attribute is modified manually, it can cause authentication issues and prevent users from logging on to the domain.
DFS Replication issues: The dSCorePropagationData attribute is also used by the DFS Replication service to track replication status for DFS shares. If this attribute is modified manually, it can cause replication issues and prevent files from being replicated properly between DFS shares.
Inconsistencies in the domain: Modifying the dSCorePropagationData attribute manually can cause inconsistencies in the domain, which can result in data loss or corruption. This can affect the entire Active Directory infrastructure, making it difficult to manage and maintain.
In general, it’s recommended to only modify the dSCorePropagationData attribute under the guidance of Microsoft support or a qualified Active Directory expert. This can help prevent issues that can arise if this attribute is modified manually.
So, that’s all in this blog. I will meet you soon with next stuff .Have a nice day !!!
