Hi,

I have a client (C# MS Excel Project) calling a Web Service to retrieve and
update data. One of the business requirement is the client's NT Login ID, IP
Address and computer name must be log for each web service method call.

To get client information using integrated Windows authentication with
ASP.NET client. You need to disable "Anonymous Access" and enable
"Integrated Windows authentication". IE will automatically pass in the
authetication information to IIS.

Since I am not using IE to call the Web Service, IIS could not retrieve
authentication information. How can I fix that limitation?

Thanks,
