I'm assuming that you must have an NTLMv2 network/proxy.  If so, then 
this page explains why excluding the httpclient provider works:

Not specifically...and that's because ECF uses the Eclipse platform 
proxy API to detect/use proxy configuration information.  So I think 
that all you would have to do to configure proxies differently is to 
also use the proxy API (or just use the Eclipse preferences UI under 
General->Network Connections...which uses the Eclipse platform proxy API 
underneath).

Note that the current version (Eclipse 3.5) proxy API does *not* support 
transparent detection/configuration of NTLMv2 proxies.  This is 
something we/ECF are working on with Pawel of the platform team in bug 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=252002  (see comments 60, 
61, and comment 64).

> 2. where can we find the possible configuration options for ECF ?

As outlined above, ECF uses the platform proxy API to get proxy 
configuration.  So if you want to setup the proxy info for your app, and 
have ECF filetransfer use it, you can either use the proxy API 
programmatically (and have your own user interface), or even use the 
Eclipse preferences User interface.

Please let know if you would like more info, obviously with bug 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=252002 and the need to 
workaround httpclient and NTLMv2 issues much of this is in flux right now.
