Full Text Search FTSFacade Unauthorized issue EPiServer 6 R2

Question

I'm using Windows Authentication in IIS and whenever I try to run Full Text Search index job from adminmode the errorlog gives me this and the Full Text Search service cannot build the index (Main and Ref folders):

2013-04-29 11:09:00,898 [65] EPiServer.Search.RequestHandler.GetNamedIndexes(:0) - Could not get named indexes for uri 'http://epi.hfabintranetv2/IndexingService/IndexingService.svc/namedindexes/?accesskey=E8308A19-5FC4-484C-8E85-C9987884CD07'. Message: The remote server returned an error: (401) Unauthorized. at System.Net.HttpWebRequest.GetResponse()

Message: 'The remote server returned an error: (401) Unauthorized. at System.Net.HttpWebRequest.GetResponse()

at EPiServer.Search.RequestHandler.SendRequest(SyndicationFeed feed, String namedIndexingService, Collection`1 ids)'

I've noticed that setting Anonymous Authentication to Enabled in IIS lets Full Text Search service create the index (Main and Ref folders).Any clues on why it is not rebuilding the index while using Windows Authentication?

Answer 1

The answer was to set Windows Authentication on the root folder of your site and then settings the IndexingService folder where the .svc file is, to Anonymous Authentication.
