      Hi
      One of my DC is generating this event after every 5 min,

      Event Type: Error
      Event Source: NTDS General
      Event Category: DS Schema
      Event ID: 1136
      Date: 10/24/2009
      Time: 10:17:30 AM
      User: NT AUTHORITY\ANONYMOUS LOGON
      Computer: DC02
      Description:
      Active Directory failed to create an index for the following attribute.

      Attribute identifier:
      2339952713
      Attribute name:
      msExchRoleFlags

      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

      These errors are logged every 5 minutes and are also logged for the
      following attributes:

      msExchRoleFlags
      msExchObjectID
      msExchThrottlingIsDefaultPolicy
      msExchRoleEntries
      msExchRoleAssignmentFlags
      msExchScopeFlags
      msExchLicenseToken

      After extending the schema, we allowed replication to occur on all our
      domain controllers and did not receive any errors when extending the schema.

      successfully upgraded Exchange 2007 HUB CAS to exchange 2007 SP2 Update Rollup 1

      Please advise how to fix this

      Hi,

       

      The attributes (msExchRoleEntries, msExchThrottlingIsDefaultPolicy, msExchRoleFlags, msExchObjectID, msExchRoleAssignmentFlags) reported in the event log are not used by Exchange 2007. They are for Exchange 2010. Exchange 2007 SP2 includes Exchange 2010 Schema extension.

       

      So changing the Schema for these attributes won't affect searches until Exchange 2010 is utilized in the environment. We can choose not to index those attributes.

       

      Note: Active Directory Schema provides an option to index an attribute for container searches.

       

      1.    Please check the language pack from following registry

       HKEY_LOCAL_MACHINE\Software\Microsoft\NTDS\

      2.    Please check the language that you used for DC from Control panel -> Regional and language options -> Details

      3.    Compare the value and then install the right language pack for the computer.

      4.    After that, we need to uncheck “index this attribute for containerized searches in the active directory”

      a.    Please type MMC from a command prompt and then click OK .

      b.    On the Console , File->Add/Remove Snap-in->Add->Active Directory Schema .

      c.    Click Add and close. Click OK to add the snap-in to the console.

      d.    Expand the active directory Schema to where you see classes and attributes. select attributes. on the right side select the attribute.

      e.    Uncheck the box "index this attribute for containerized searches in the active directory".

      f.     After that hit apply then ok. select the top of the snapin where it says active directory schema right mouse click and select " Reload the schema"

      Finally, please wait for some minutes and then check the event again.

       

      Regards,

      Xiu

      Remove the "Index this attribute for containerized searches". Follow this for reference http://technet.microsoft.com/en-us/library/cc739174(WS.10).aspx

      Do you have any unsupported language pack? Uninstall it and then see if you still get this errors.

      Remove the "Index this attribute for containerized searches would not harm anything so i have to uncheck the "Index this attribute for containerized searches" for all below attributes

      msExchRoleFlags
      msExchObjectID
      msExchThrottlingIsDefaultPolicy
      msExchRoleEntries
      msExchRoleAssignmentFlags
      msExchScopeFlags
      msExchLicenseToken


      so also where to check unsupported language pack  ?
