401 While Accessing Web Service

Ben
I'm trying to access a c# web service from a web form.

I set up the web reference proxy object as follows:

proxy.PreAuthen ticate = true;
proxy.Credentia ls = CredentialCache .DefaultCredent ials;
but i get a 401 error. If I switch the IIS website from Integrated
Windows Auth to Anonymous, it works... but i want it to use windows
security.

my web.config of the web form is set to imperonsate the logged on
user, and i verified that's working by checking that
this.User.Ident ity.Name is my domain user (which has access to the web
service).

Any ideas what i'm doing wrong? (btw, the web service is SSL if that
makes a difference).

Thanks!

thanks,
anyway to do it without using web form authentication?

the crazy thing is that if i fire up my web form from Visual Studio it
works just fine and can access the web service, but if i publish it to
another server and try from there I get the 401 (the site i'm
publishing to is using 'intergrated windows auth') .

okay, check WSE (Web Service Enhancement) to see how to improve the web
service security..

to avoid the dependacy with integrated authentication, create a new web site
for your web service, that way it should work fine.

I'm using VS2008... is there WSE for that version? i can only find it
for VS2005?

is this the only way? i made C# web services before that were hosted
on an IIS site with intergrated windows auth, but the client side was C
++ and i was able to pass current nt credentials without a problem....
this is my first attempt where the client side is another c# web page.

I am not sure whether this is the only way.. When you say it worked with C++
and now is not working with aspx/c# web site, that is interesting..

The WSE 3.0 should work fine with framework 3.0/3.5. But if you want it to
work with VSS 2008 IDE then you need to trick it.

e.g.:-

But I din't do this.. so please do it with extra care..

You need to get the web service configure into a another web site, then you
can remove the integrated authentication just for that web site.. then your
web service will be vulnerable, so to improve security use the WSE..

just converting the project to 2005 and enable wse won't do any good. as the
webservice is still having integrated security..

so are u saying I cannot use integrated security on a WS?

btw, it works fine if my client is a C# windows form (instead of a web
form)... so I think this shows the WS is okay... it's just there's
something i'm missing on the web form to make it work... but
everywhere i read i see they just say to set the Credentials param and
i did that already.

you are hitting the one hop rule with nt creditals. it should work if you hit
the web site locally, but not from another computer.

to do this you have two options:

1) switch to basic, which will give the web server a primary token it can
use to access a second server.
2) switch to kerberos and enable server credentials delegation.
