I have 2 Srv 2003std DC's and I installed our first Srv 2008std box. I did the domain and forest prep and it said it finished fine - at least it looked fine.
Then I ran dcpromo on the Srv 2008 box and that seemed to go fine until I noticed that one of the original Srv 2003 DC's was spitting up errors in the event log. Several NTDS errors - Active Directory failed to create an index for the following attribute.
A schema cache update will occur 5 minutes after the logging of this event and will attempt to create an index for the attribute.
-1403 JET_errIndexDuplicate, Index is already defined
NTDS entries all look fine on the newly created Srv 2008 DC. What can I check on the original DC's to see what went wrong with the forest and domain prep for 2008 ?
