Thanks gentlemen. Your feedback is greatly appreciated.

It looks like my legacy Delphi app was not using ICS, hence the UseWinInet, 
however the current C++ app is using the library OverbyteIcsBcb100Package. Can 
I assume this is version 6 of Overbyte ICS or is it prior?

My follow on question is which params/properties do I need to set when 
configuring my HTTP client (OverbyteIcsBcb100Package) for NTLM. It works fine 
for No & Basic Authentication but when I configure for NTLM one of my clients 
is reporting a failure i.e. cannot download the data. Currently I have the 
following properties configured when download via NTLM:

                        HttpCli->ProxyAuth = httpAuthNtlm;
                        HttpCli->ProxyUsername = ProxyUser;
                        HttpCli->ProxyPassword = ProxyPass;

Thanks in advance.

That was my first thought, except the line:

> HttpCli->ProxyAuth = httpAuthNtlm;

does look remarkably like ICS, so I'd guess the programme is using two
different internet libraries, maybe because it preceded NTLM being added
to ICS in 2004?  

Stripping out all the WinInet code is probably the first step, to ensure
all the correct ICS component properties are being used.
