Hi, It is clear that for the configuration you are running NTLM is not authenticating properly.
I would run the Http class with TRACE logging activated, this will show the credentials you are after. You should also note the documentation in nutch-default.xml which explicitly states "NOTE: For NTLM authentication, do not prefix the username with the domain, i.e. 'susam' is correct whereas 'DOMAIN\susam' is incorrect."... looking at your log this does not seem to be the case. http://svn.apache.org/repos/asf/nutch/trunk/src/plugin/protocol-httpclient/src/java/org/apache/nutch/protocol/httpclient/Http.java -- *Lewis*
