 - If running cmdlets from an Active Directory provider drive, the default value of **Partition** is automatically generated from the current path in the drive. 
 - If none of the previous cases apply, the default value of **Partition** will be set to the default partition or naming context of the target domain.
 
-In AD LDS environments, a default value for Partition will be set in the following cases: 
-
-- If the **Identity** parameter is set to a distinguished name, the default value of **Partition** is automatically generated from this distinguished name. 
-- If running cmdlets from an Active Directory provider drive, the default value of **Partition** is automatically generated from the current path in the drive. 
-- If the target AD LDS instance has a default naming context, the default value of **Partition** will be set to the default naming context.
-To specify a default naming context for an AD LDS environment, set the **msDS-defaultNamingContext** property of the Active Directory directory service agent (DSA) object (**nTDSDSA**) for the AD LDS instance. 
-- If none of the previous cases apply, the **Partition** parameter will not take any default value.
+The parameter is only useful for snapshots. On live AD domains, the domain NC is the only allowed partition, relative to the value of the “-server” parameter.
