I'm using the sample code comes with WSS 3.0 SDK see below..

//The string containing the keyword to use in the search
string keywordString = "Microsoft";
//The XML string containing the query request information
//for the Web service
string qXMLString = "<QueryPacket xmlns='urn:Microsoft.Search.Query'>"+
"<Query><SupportedFormats><Format revision='1'>"+
"urn:Microsoft.Search.Response.Document:Document</Format>"+
"</SupportedFormats><Context><QueryText language='en-US' type='STRING'>"+
keywordString + "</QueryText></Context></Query></QueryPacket>";
QueryWebServiceProxy.QueryService queryService = new QueryWebServiceProxy.QueryService();
queryService.Credentials = System.Net.CredentialCache.DefaultCredentials;
System.Data.DataSet queryResults = queryService.QueryEx(qXMLString);
resultsGridView.DataSource = queryResults .Tables[0];

But its throws exception like this...

Server was unable to process request. ---> Attempted to perform an unauthorized operation.

Line 142:        [System.Web.Services.Protocols.SoapDocumentMethodAttribute("urn:Microsoft.Search/Registration", RequestNamespace="urn:Microsoft.Search", ResponseNamespace="urn:Microsoft.Search", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
Line 143:        public string Registration(string registrationXml) {
Line 144:            object[] results = this.Invoke("Registration", new object[] {
Line 145:                        registrationXml});
Line 146:            return ((string)(results[0]));

Can you help me in this?

Thanks in advance.

Hi, you need to change the code to set the queryService PreAuthenticate to true and the URL property

        queryService.Credentials = System.Net.CredentialCache.DefaultCredentials;
        queryService.PreAuthenticate = true;
        queryService.Url = "http://localhost/_vti_bin/spsearch.asmx"; 

 Hope that helps.

Hi, Thanks for reply.

But it throws same exception even after setting PreAuthenticate and Url properties.

We have domain users for the SharePoint Portal and the same is working. Its working good, if I try to test service through IE(http://localhost/_vti_bin/spsearch.asmx). But through ASP.NET application it throws the exception.

Should I set any explicit authentication for this? Help me in this.

Thanks in advance.

Hi,

I meet the same problem when I use web service executing MOSS search, eventually I manually set IIS authentication to use only windows integrated authentication(uncheck the anonymoys thentication), then it is work.

I think IIS always ignore the passing token if the anonymoys ahtntication is checked, so the taken passed from IIS to MOSS is the account running IIS(such as IIS_MachineName). That is why got security exception.

Regards

Also add the following line in web.config

<identity impersonate="true">
