Subject RE: Problems with NTLM authentication
Date Fri, 21 Nov 2003 17:52:11 GMT
Hi Khalid

Thanks for the prompt response. Your code produces the follwoing message;

INFO: Already tried to authenticate with 'null' authentication realm at www-proxy2.uk.int.atosorigin.com,
but still receiving: HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires
authorization to fulfill the request. Access to the Web Proxy service is denied.  )

Regards
Roger
