Lili, Truth to be told, NTLM proxy + NTLM host authentication has never been properly tested, because none of us (HttpClient developers) has got access to a Microsoft Proxy installation. I would not be surprised if it did not work at all with HttpClient 2.0. I know for a fact that BASIC proxy + NTLM host should work. I have been using Squid proxy to run the tests, though.
Anyways, could you please get hold of the latest HttpClient DEVELOPMENT snapshot from the following location and see if it produces the same results? <http://cvs.apache.org/builds/jakarta-commons/nightly/commons-httpclient/> It is much easier for me to troubleshoot the development version of HttpClient because it's authentication code has become much saner. Authentication code has undergone a complete rewrite for the 3.0 release and _should_ be significantly more robust than that of HttpClient 2.0. Once the problem is idenified and fixed, I'll port the changes to the stable HttpClient branch Please note that the development version (which is going to be the version 3.0 when released) is no longer 2.0 API compatible. You may have to make some adjustments to your code.

I have 401.1 error when both IIS are set up using NTLM and proxy server is Basic or NTLM. The proxy server set up code is as follows: (NTLM case) client.getState().setAuthenticationPreemptive(false); client.getHostConfiguration().setProxy("<proxy IP address>", 80); client.getState().setProxyCredentials(null, "<proxy IP address>", new NTCredentials(proxy-server-username, proxy-server-password, proxy-server-host, proxy-server-domain)); The web server connection is done as follows: client.getState().setAuthenticationPreemptive(false); client.getState().setCredentials( null, "10.8.9.22", new NTCredentials(username, passwd, "10.8.9.22", "INXIGHT"); Other combinations work well (IIS basic + proxy NTLM or proxy basic) IIS NTLM without proxy server also works. Log file is attached.
