Hello, I am looking for a solution of strange Problem. It seems that WinHTTP Programs under Windows 7 tend to use Kerberos Authentication, instead of NTLM. The problem is, that I am working behind a Squid Proxy that is only configured for NTLM. Do somebody know which settings I should modify? Is there a setting required for "Network security: LAN Manager authentication level" under Windows 7? Are there known problems with such a configuration or any FAQs for troubleshooting such environments? Kind regards Wolfgang
