TREX error - Code 6401

Hi all,

While indexing my KM documents i receive the following errors (on 410 files):

[01220] 2009-01-12 16:40:28.841 e preprocessor Preprocessor.cpp(00798) : HTTPHEAD failed for URL <filename> with Httpstatus 401

[01220] 2009-01-12 16:40:28.856 e preprocessor Preprocessor.cpp(03393) : HANDLE: DISPATCH - Processing Document with key <filename> failed, returning PREPROCESSOR_ACTIVITY_ERROR (Code 6401)

I've tried applying the note 650521 (add the entry unescape_url= no into the httpclient section of the TREXPreprocessor.ini) but that didn't help.

The other (thoused of) documents are indexed OK.

Regrads,

Aviad
