Unable To Pass User Credentials From WCF Web Service To ASMX Web Service
May 25, 2010
My WCF Client calls my WCF Service which then calls ASMX Web Service. The problem is i have configured my wcf client and wcf service to windows credentials type but when wcf service calls asmx service the user credentials (default windowsidentity) is not passed to asmx service.
In WCF Service i am able to get user identity by using : Thread.CurrentPrincipal.Identity.Name;
WCF Service - i have disabled anonymous access and enabled windows authentication. ASMX Web Service - i have disabled anonymous access and enabled windows authentication.

Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?
I have a silverlight application that uses WCF service and i need to provide windows authentication using wcf.In order to achieve this i am trying to retrieve the client's credentials (windows credentials)inside wcf.
My scenario is this - I have two ASP.net websites. Both sites run on the same machine and I have implemented single sign on relatively simply using the default asp.net membership provider (Forms based authentication).I have a new WCF service on one site, which will be called from the other site. A user will be logged into the site, but the call to the service will be made from the codebehind following a postback.Can somebody point me in the right direction so that I can pass through the Forms based credentials of the logged in user to the WCF service on the other site? Presently it's passing the NETWORKSERVICE windows credentials.
I'm running an ASP page that is using a WCF client to get some data. How can I set/pass the Network Credentials (of the user that performed the request, not the .net pool thread) on the WCF client so the WCF service will be able to perform impersonation using these credentials ?

I have a web service which is accessible from the browser. When I try to access the same web service which is hosted on Windows Server 2008 R2, from an excel Macro, it says
Run-time error '-2147220991' (80040201)':
Server was unable to process request --> The request failed with HTTP status 404: Not Found.
The excel macro works fine when I try to access the same web service on the other server(Windows 2000 Server)
The web service is developed using .Net 2.0.
I'm posting the URL for the web service for your reference.
URLs which are not being accessible from Excel.

Both Web services and Excel macros are old applications which have been running fine for years. The only change is that the application is being migrated to a new server(MCDEAGDWEB202) which has Windows Server 2008 R2 and SQL Server 2008.
The Old server(MCDEAGLWEB005B) has Windows Server 2000 and SQL Server 2000.
I have added a web service as a reference to a windows application using "AddWebRefrence" option. And I am unable to access the funtions in the web service but instead i get the functionnames followed by the completedeventargs and completedeventhandler.
What am I doing wrong and how can i access the funtions in the web service.
I would like to pass xml document to a method in WCF service by client that server will get xmldocument,parse it and send back the xml response.What are best practice for thi?The xml document is conform to XSD so i would like to create managed type that represent the schema and then expose thatIf anybody has done it before or know any example please point it out so i can see it.
Cannot find a simple example that will call POST a service with username pass argument.
So, how to get the length of the service.
Code: Dim encoder As ASCIIEncoding = New ASCIIEncoding Dim data() As Byte = encoder.GetBytes(rawresp) Dim request1 As HttpWebRequest = CType(WebRequest.Create("http://www.sas.gr/MobileService/MobileService.asmx?wsdl&op=getCinemaMoviesProgram"), HttpWebRequest) request1.Method = "POST"
[Code] ...
Complains about wrong bytes. I can make it work with GET but i only get the schema.
Code: Dim request = DirectCast(WebRequest.Create("http://www.sas.gr/MobileService/MobileService.asmx?wsdl&op=getCinemaMoviesProgram"), HttpWebRequest) request.Method = "Get" ' request.ContentLength = 0 request.Credentials = New System.Net.NetworkCredential("WSl", "WSs") Dim response1 = DirectCast(request.GetResponse, HttpWebResponse) Dim reader = New StreamReader(response1.GetResponseStream()) Dim rawresp As String rawresp = reader.ReadToEnd()
This will only give the schema back, no data. Also if i reference the service there is no getCinemaMoviesProgram function to call, so I suppose it only works with post.
I receive the following error, when trying to consume Wcf service:
"An existing connection was forcibly closed by the remote host". Consuming the service works fine when the host and the client are on the same machine. When I move the client to Hyper-V virtual machine (I didn't try it on a real computer) - it throws the error. Both firewalls are turned off Do you know what can cause such behaviour? Here are the details:
Both the client (hyper-v) and the service are on Windows server 2008 R2
Service url - http://wcftest/CalculatorService.svc (wcftest is the website and is mapped in the hosts file to localhost)
Service config:

Client config:

Are there any configuration settings which I'm missing?
I am a newbie to ASP.NET (but not to C#)I have a project I am developing that may seem unconventional at this point but it is a project that I hope to eventually expand and provide a new type of service on the internet. Currently the project makes use of an Excel spreadsheet that is generated by another application I wrote. Basically the spreadsheet is an index to a specific type of file that exists on a host computer and the files are directly linked from within the excel document. When the link is clicked it opens the file using the operating system default program which then processes the file (this takes some time).
This is fine and dandy but when I click on another file, the default program immediately stops processing one file and opens the latest submission and thus interrupting the previous job. To prevent this I am now writing a queuing application. Here is where ASP.NET comes in. I do not want the link to open the queuing application with the file to add into the queue as a parameter because that pops one or more nnoying/scary "you are opening an executable" dialogs and because I want to be able to access the queuing service from a remote computer, and possibily in the future over the web. Instead I am trying to use an ASP.NET service application that will accept the name of a file as a parameter, access the external queue class (defined in an external dll of which only one universal instance is allowed), and add the request to the queue. Whether or not the table is an excel table or on a web page, using a form in this instance is tedious, not only for me but for a user. I want the user to be able to simply click on an html link and have the file be queued without anything except maybe a confirmation page pop up saying that the file has been queued and it will take x amount of time before the file is finished processing.
My problem is I cannot for the life of me find a way to do this. I have searched the interenet for over a week now looking for a way to call a "WebMethod" using a link and I am getting the impression that it cannot be done. Even when I use a form and try to have the form pass a string (representing the file name) as its "action" it comes up with an application error saying that I am missing the parameter I am trying to pass. Here are some examples of what I have tried:Here an example method I would try to access:

Here is an example of how I tried to access directly by way of a link (which results in an application error: InvalidOperationException)"
How to create an instance of web service without adding web service reference? How to identify the server address/name where the web service is hosted from C# code?
i have created a normal web service and i want to host it outside IIS. one idea i got is to use window service as hosting environment. i have created a web service and hosted it window service and its window service is running now.would anybody please let me know that how can i call web service hosted in window service binded over soap.tcp. here is my sample code.
I am keep getting an error that "Service Error : wbsTest failed" where wbsTest is my webservice.
The error comes up frequently enough for the user - normally reproducible within a minute or so of working with an application.
A bit of background: An user is a remote user accessing application hosted on our servers over https. He is software firewalled and his connection isn't the fastest but it is responsive enough. When errors do not present themselves, page loads are fairly quick.
