Hi Experts. Seem to be getting the below errors every 5 minutes in the Directory Service Event logs on my DCs. Anyone come across this before?

Active Directory failed to create an index for the following attribute.
 
Attribute identifier:
2664273139
Attribute name:
msRTCSIP-ApplicationDestination
 
A schema cache update will occur 5 minutes after the logging of this event and will attempt to create an index for the attribute.
 
Additional Data
Error value:
-1403 JET_errIndexDuplicate, Index is already defined

- Open Active Directory Schema (add the snap-in to MMC if necessary)
- Click on the Attributes folder (not Classes)
- Scroll down until you find msRTCSIP-ApplicationDestination
- Right click on it and select Properties
- Uncheck the last checkbox "Index this attribute for containerized searches in the Active Directory"
- Click Apply
- Done!
- Check Directory Services in the Event Log to make sure that index was deleted.

PeteLong - Thanks for that. I have made the change, just waiting to see if a new event is generated. If it hasn't reappeared in the next 10 minutes i will close the question and award the points. Again thanks for the prompt response!!
