http status code 401 : unauthorised

Hi all,

We are using EP6 SP9 with KM SP9, TREX 6.1 SP9. We are using file system based repositories with custom properties for upload & search.

Indexing fails with 'Queue entry' showing the documents as 'Preparation failed' with return message "http status code 401:unauthorised".

Has anyone come across this error ? Please suggest ways to rectify.

Thanks & regards,
