Authentication Methods

[Rohit Sood]

I have to do Authentication through code written (Vb 6.0). My problem is when we
are doing testing in development and we are opening browser to do browing then at
that time one dialog box will appear with User Name and password with out that it
won't allow to browse.
I dont want that should appear.I know That , that can be removed by changing the
setting in virtual Directory ---- Basic Authentication to uncheck. And allow
anonymous user.
I had written code also to handle that one .... with some API but its a EXE . And
that exe should be loaded on each client so that when ever any dialog box will
ask User Name and password it will by pass that one . ( with hard code User NAme
And password)
But in this we have to download Exe to each client.
Now my problem is Is there any way by which i can know which client is coming (
computer ) is try to access the web site so that i can get handle for this client
and i can remove the dialog box which is going to appear ( User Name , Password).
If any test code are there then please send me.
Thanks,.....
