Hello,
i have problems understanding the modifiedTimeStamp attribute especially in the schema. I found on MSDN and Technet that this attribute is computed from the whenchanged attribute of the same object. If you look at the attibutes “whenchanged” and “modifiedtimestamp” from cn=Schema,CN=Configuration,DC=Contoso,DC=com you can see that these 2 attributes have the same value. This is also the same for every other object under schema except:
If you take the Object “CN=Aggregate,CN=Schema,CN=Configuration,DC=Contoso,DC=Com” which clients use to update their local schema cache you can see that “modified timestamp” differs from “whenchanged”.
On Server2008R2 the “modifiedtimestamp” Attribute of “CN=Aggregate,CN=Schema,CN=Configuration,DC=Contoso,DC=Com” equals the “whenchanged” attribute of the Schema.
On pre Server 2008R2 the “modifiedtimestamp” Attribute of “CN=Aggregate,CN=Schema,CN=Configuration,DC=Contoso,DC=Com” doesn’t equal the “whenchanged” attribute of aggregate neither the whenchanged attribute of the Schema.
Can someone tell me the background of the computing of the modifiedtimestamp attribute of “CN=Aggregate,CN=Schema,CN=Configuration,DC=Contoso,DC=Com” and why the computing differs from 2008R2 and pre2008r2 and also how the attribute is computed under 2008R2?
Thanks
