I can type USER ID & PASSWORD and when I click INVOKE I get approval. When I try to add web refence to my web site for using web service I get error "The request failed with HTTP status 400: Bad request: request-line invalid." and I cannot add reference. [URL] What could be the problem?

I created aMicrosoft.Reporting.WinForms.ReportViewer with a window application. It worked fine when I was in net A with domain A. My application is now moved to net B with domain B. However when I login to my computer I still login netA with domain A, userID and password for A. I then use a A/B switch to switch to net B to run my application running ReportViewer (no login directly to B). But when I run ReportViewer I got errors like below.
The request failed with HTTP status 401: Unauthorized.

I am trying to call webservice from my web application. The web application had integrated windows authentication. I've written custome principal class to do authorization. But when I give call to my web service with default credentials it gives me 'the request failed with http status 401 unauthorized.' error.
When I give call to my local webservice it is running fine (It also has integrated windows authentication) But when I add reference of same web service from QA server I am getting this error. Not sure what is happening. I also tried
WS.PreAuthenticate = false;
WS.Credentials = System.Net.CredentialCache.DefaultCredentials;

I have a asp.net c# web application with contains reports in remote processing mode. I am using the report-viewer control to render the reports. When I run the application in debug mode, I'm able to view my reports however when I publish the application to a different server I get this error message:The request failed with HTTP status 401: Unauthorized.
My report server is on a different server than the location of my published web application. I have added new role assignment to my report server and also added to my web.config but the error persists. I think I am missing something in my aspx page for reportviewer.

I am connecting to remote server for web service using ASP.NET 3.5 web site. something like, [URL]. Remote server is providing digest authentication to access the web service. I dont have access to modify authentication on the remote server but I have an windows account on that server. If I try to Access service WSDL through programming I get the following error:
The request failed with HTTP status 401: Unauthorized. Same web service if I try to access through browser, [URL], it asks for user name and password. Entered windows account user name and password, still getting error: You are not authorized to view this page, HTTP Error 401.1 - Unauthorized. How to pass the digest authentication credentials to the web service through visual studio or any other programmatic method?

webservice.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
What alternatively can I use to get credential inside and outside of my net?

I am calling a remote service and authenticating using a certificate. When testing with a Console App, everything works fine. When calling from an ASP.NET Website (.NET 4.0, IIS7) I receive a response code of 401 -- Unauthorized.I am adding the certificate using code such as:
var client = new TheGeneratedProxy();
client.ClientCertificates.Add(new X509Certificate("D:cert.pfx", "myPassword"));
(NOTE: I have also loaded the .pfx into the local Certificate Store using IE. The certificate is loaded into my "Personal" store -- so I suspect this to be the problem, since the Website will be running under a different account.)

I have a reportviewer control which is running well on a form. I dont receive any error message. I can pass parameters successfully.The problem starts after placing Reportview control into a grid. I need several reports for different parameters at the same time. In this case, i receive boring "The request failed with HTTP status 401: Unauthorized" error. There is no reason to receive this message as reportviewer working on the form seperate.Is there any restriction not to use ReportViewer in the gridview.codes below.

I am trying to add Failed Request Tracing to my IIS 7/ASP.NET server.
First, I create failed request tracing for "all content, error codes 400-999" because want to save all errors.
Then, I try to create a trace for "all content, time: 5 seconds" because I want to trace all "long" requests. However, IIS 7 gives me an error: "A failed request trace for this content already exists".How can I add this second trace for all content that takes > 5 seconds?

I'm writing an HTTP handler in ASP.NET 4.0 and IIS7 and I need to generate a file-not-found condition.
I copied the following code from Mathew McDonald's new book, Pro ASP.Net 4 in C# 2010. (The response variable is an instance of the current HttpResponse.)
response.Status = "File not found";
response.StatusCode = 404;
However, I found that the first line generates the run-time error HTTP status string is not valid.
If, instead of the lines above, I use the following:
response.Status = "404 Not found";
Then everything seems to work fine. In fact, I even see that response.StatusCode is set to 404 automatically.
My problem is that I don't want this to fail on the production server. So I'd feel much better if I could understand the "correct" way to accomplish this. Why did the first approach work for Mathew McDonald but not for me? And is the second approach always going to be reliable?

When I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.

I there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.
public void Init(HttpApplication context) {
context.AuthenticateRequest += new EventHandler(AuthenticateRequest);
}
protected void AuthenticateRequest(object sender, EventArgs e) {
app = sender as HttpApplication;
if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) {
// a few requests do not enter here, but my webservice class still executing
// ...
}
}
I have disabled HTTP POST and HTTP GET for webservices in my web.config file.
<webServices>
<protocols>
<remove name="HttpGet" />
<remove name="HttpPost" />
<add name="AnyHttpSoap" />
</protocols>
</webServices>
Looking at ContentType for soap+xml only partially solves my problem. For example,
Cache-Control: no-cache
Connection: Keep-Alive
Content-Length: 1131
Content-Type: text/xml
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: ro
Host: localhost
mymethod: urn:[URL]
Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).

I develop an asmx web service (i.e. ASP.NET 2.0). There's a piece of code that may read the contents of the HTTP request (via HttpContext.Current.Request.InputStream) while processing it. I realise that InputStream may only be read once for a request, and I make sure I never try to read it more than once.
The problem seems to be that if InputStream happens to be read during the early stages of the application's lifecycle (e.g. after pskill w3wp, during Application_Start), the HTTP request fails with a HTTP 400 - Bad Request error, with no explanation given, no exception thrown and no entry in the httperr log. If it is read later (e.g. within the web method itself), requests run fine whether InputStream is read or not. Application_Start runs fine if InputStream isn't read.
Is this some sort of ASP.NET bug? IIS bug? Or am I doing something wrong by daring to read InputStream? And if so, is there another way to get a look at the "raw" contents of the request without disturbing the inner workings of IIS/ASP.NET? In short, adding this code within Application_Start is enough to reproduce this error: using (StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream))reader.ReadToEnd();
