Back in April KB980360 was released. It had a nice description of the changes in the BPA for the Active Directory Domain Services. Some days ago the update was finally made available for download… And now the KB is gone. Weird.
The update can be downloaded here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=45a9c434-163f-47ed-a285-60e1c0b988b9
There is also a link to the knowledge base article but it’s not working as well.
I remember the BPA had some new checks regarding Service Principal Names (duplicate check amongst others)
