I hosted silverlight application iis and that can be accessed in multiple ways..
When I access using Qualified name of server IP address IT WORKS fine:
http://[QUALIFIEDNAME]/WebUAT/App.aspx
When I access using IP address like below:
http://[IPADDRESS]/WebUAT/App.aspx
It gives error below:
[Async_ExceptionOccurred]
Arguments:
Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.1.20913.00&File=System.dll&Key=Async_ExceptionOccurred StackTrace : at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary()
Follow these,
(i) Try to use fiddler and find the request which is making crossdomainpolicy xml request.
(ii)Check whether it is failing, if so add the crossdomain and clientaccesspolicy to the root folder of your Application
(iii)Check whether the service which is invoked by your application is blocked by firewall.

I have REST service application which is hosted in an IIS 8 in a Windows 8 PC. When I request the service I am getting an error as follows ... HTTP Error 404.0 - Not Found.
Here is the detailed error message.
HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
Most likely causes:
•The directory or file specified does not exist on the Web server.
•The URL contains a typographical error.
•A custom filter or module, such as URLScan, restricts access to the file.
Things you can try:
•Create the content on the Web server.
•Review the browser URL.
•Create a tracing rule to track failed requests for this HTTP status code and see which module is calling SetStatus. For more information about creating a tracing rule for failed requests, click here.
Detailed Error Information:
Module IIS Web Core
Notification MapRequestHandler
Handler StaticFile
Error Code 0x80070002
Requested URL http://IP.com/Wining/RService.svc/general
Physical Path C:\inetpub\wwwroot\Wining\RService.svc\general
Logon Method Anonymous
Logon User Anonymous
Any help on this would be greatly appreciated.
There are myriads of possible causes. In general, the target resource at given URL is not found, so it may be simply missing, misconfigured, not started, etc. First - check the server logs, they usually contain more detailed information about the issue.
Also, please doublecheck that the service really is up and running. Connect to the www server and check it via localhost not ip.com.
I'm not an expert, but judging from the snippet you provided, it seems to be WCF service, the Handler: StaticFile seems very odd. It seems like the IIS misinterpretes your request as a StaticFile (a resource read from the disks and just passed-through without any further processing) which for me seems perfectly wrong.
You may have not installed the service properly, or have url mappings and/or handlers messed up, or you may even have NET/ASP framework not properly installed.. What have you installed first? .Net or IIS?
check similar questios, there are many.. for example:
WCF on IIS8; *.svc handler mapping doesn't work
HTTP 404 when accessing .svc file in IIS
I had to enable HTTP Activation in .NET Framework 4.5 Advanced Services > WCF Services (running on WIndows 2012) and after an IISReset it worked fine.
I have added a WCF service to an existing ASP.Net web project on our test website (only accessible on company network). I can access the service by typing the URL in a browser, but if I add a service reference to a web project, I get a runtime error that 'the remote name could not be resolved'.
In my web.config, I have the bypassProxyOnLocal binding attribute set to 'true' (we use a proxy on the company network), but it seems as though our test domain is not recognized as a local domain (or recognized at all, really). Again, this is only when I add it as a service reference. Obviously the domain is valid, because I can add it as a service reference, and can event paste the URL into a browser, and it works. I just get a runtime error after I add it as a service reference. Anyone have any advice?
According to MSDN WSHttpBindingBase.BypassProxyOnLocal Property, "An Internet resource is local if it has a local address. A local address is one that is on same computer, the local LAN or intranet and is identified, syntactically, by the lack of a period (.) as in the URIs "http://webserver/" and "http://localhost/".
If your test domain is "http://test.mycompany.com/", then it won't be viewed as a local address. Perhaps using "http://test/" in this case would work?
Finally got this resolved. The request was somehow being blocked by the company network.
I have a website running 2 WCF services. Working awesome until I needed to move them from the "Default Web Site" in IIS7 to a dedicated website with a new IP address. Now I get the error message:
"...could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name"
ALL I did was change:
net.tcp://localhost/...
TO:
net.tcp://10.1.2.204/...
I have changed every spot in my configs which once used localhost to specified IP address. The new website is setup exactly the same with the proper net.tcp bindings and it is bound to the single IP address of 10.1.2.204.
I cannot seem to figure out what is going on. I am looking at the svc trace logs and all I get is a bunch of the same.
My new website is called "core" whereas previously I was hosting on "Default Web Site". I added a new FQDN/public IP to route to this new site (backwards to the mentioned private IP address). Now my services are busted.
I know baseAddress is ignored when using IIS/WAS hosting, so I am not sure what else to check. I changed absolutely nothing else in the configs.
What else can I provide to help troubleshoot this?
--
I am also seeing this in the service trace viewer:
Activity Name Receive bytes on connection 'Listen at 'net.tcp://hole.myserver.com/...'.'.
...but the WCF services are actually hosted on that new "core" website which translates to my new private IP address. I have change FQDN names for the example. To make it clear:
I used to have 1 FQDN on this server using Default Web Site.
I now added a 2nd FQDN to this server, new website, second IP. It seems to me that the listening should be directed towards: net.tcp://core.myserver.com instead of net.tcp://hole.myserver.com. Let's pretend the server name is hole.myserver.com and my new website is core.myserver.com on the same server.
Hopefully this is not confusing and you can make sense of it.
I'm using the default net.tcp port of 808 and binding of 808:*
--
This is the first exception thrown that I can tell:
The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:10'.
--
None of these combos will activate the service and all produce the same exception:
net.tcp://localhost
net.tcp://localhost:808
net.tcp://10.1.2.204
net.tcp://10.1.2.204:808
even using a different port which I have done before without issue:
net.tcp://localhost:75
net.tcp://10.1.2.204:75
none of these work. :(
Thanks so much!
Its rights issue. Right click on your new website --> then Edit Permissions. On properties window click security tab and Edit button. Then Add IIS_IUSRS and give Read & Execute, List folder contents, Read permissions. Now iisreset and start to host and connect net tcp on new website.
I have developed a WCF service and, while in Visual Studio 2010, I can import the WSDL without a problem. After I've deployed it to AppFabric, I get the WSDL, but several schema files referenced internally in the WSDL cannot be found, for some reason. I don't know if it's a configuration issue, or what. The error I get when I try to process the WSDL in Visual Studio 2010 follows below:
Metadata contains a reference that cannot be resolved:
'http://myserver.mydomain.com:9871/app_deploy/MyAppService.svc?wsdl'.
The WSDL document contains links that could not be resolved.
There was an error downloading 'http://myserver.mydomain.com:9871/app_deploy/MyAppService.svc?xsd=xsd0'.
The request failed with HTTP status 502: Proxy Error ( The
specified network name is no longer available. ).
Metadata contains a reference that cannot be resolved:
'http://myserver.mydomain.com:9871/app_deploy/MyAppService.svc'.
There was no endpoint listening at http://myserver.mydomain.com:9871/app_deploy/MyAppService.svc
that could accept the message. This is
often caused by an incorrect address
or SOAP action. See InnerException, if
present, for more details.
The remote server returned an error: (404) Not Found.
If the service is defined in the current solution, try building the
solution and adding the service reference again.
The error is a proxy error because it goes through a proxy, but the error is because the page isn't there. I've tried accessing http://localhost:9871/app_deploy/MyAppService.svc?xsd=xsd0 at the server, but I get 404.
Why wouldn't these xsd files being found? Is it a deployment issue?
Any help would be greatly appreciated.
Man, I finally found the problem here. I needed write permission on C:\Windows\Temp for Application Pool user!
I have made a small log service that i want to publish to a subdomain on my webhotel. I make the wcf service and test it locally - no problem. I then go to the [Build] menu and choose [Publish], type in my FTP location and publishes it to the location. No problems.
The problem arise when i need to use it, i try to navigate to the .svc file but gets this error:
This collection already contains an address with scheme http. There can be at most one address per scheme in this collection.
Parameter name: item
What am I doing wrong?
That's because of your IIS configuration. This has already been discussed here: WCF service startup error "This collection already contains an address with scheme http"
Solved! The problem is that i cannot access the IIS configuration, since its on a hosted environment. The solution is described on my blog, since i had so much trouble getting this to work.
