Web Service throws 401 Error when consumed

P: n/a
I have written a web service to return information from the database. This
works and the data is returned in XML format from the database and displayed
on the web page as well when this web service called getsampledata is
invoked. Now I create a web page and created a webservice using the web
reference technique in the VS .NET to consume this web service. The web
page (application), web server, web service and database are on the same
box. Here is where my problems start. I keep getting this error message
reproduced here.

System.Net.WebException: The request failed with HTTP status 401: Access
Denied. at
System.Web.Services.Protocols.SoapHttpClientProtoc ol.ReadResponse(SoapClient
Message message, WebResponse response, Stream responseStream, Boolean
asyncCall) at
System.Web.Services.Protocols.SoapHttpClientProtoc ol.Invoke(String
methodName, Object[] parameters) at
WebPageWebServiceTest.HPSD.Service1.GetSampleData( ) in
C:\Inetpub\wwwroot\WebPageWebServiceTest\Web
References\HPSD\Reference.cs:line 40 at
WebPageWebServiceTest.WebForm1.Button1_Click(Objec t sender, EventArgs e) in
c:\inetpub\wwwroot\webpagewebservicetest\webform1. aspx.cs:line 69

Name of the web page trying to consume the webservice =
WebPageWebServiceTest
Name of the webservice HPSD.Service1.GetSampleData().
I have played around with the web config file and have the following working
web.conifg parameters
<authentication mode="None" />

<identity impersonate="true" />

Same parameters on both the web.config files ie on the web service and web
page(application). The database has aspnet configured as a user. The
following line is the connection string details on the webservice

sqlConnectionString="Provider=SQLOLEDB.1;integrate dsecurity=SSPI;Persist
Security Info=False;Initial Catalog=XXX_DEV;Data Source=XXXX;

I just am not able to get past the error noted above.

I am wondering if anyone else has run into this problem. Any pointers/tips
much appreciated.

Thanks

Sanjay

Do you have anonymous access turned on for your web application? Here is a
knowledge base article that addresses this situation and may help:

You can bind to any class that supports the IEnumerable interface:

dataGrid.DataSource = dataSet;
dataGrid.DataBind();

Actually Chris I knew that and the web service is working now like a charm.
But thanks for the reply anyway.
