I'm currently working on an Silverlight 3 project, I'm using 2 machines to test it.
"harbinger" is the web server running Win7 + IIS . I've deployed the webpage and the WCF webservice to that machine.
I've entered the following url's in my browser :
http://harbinger:43011/UserService.svc
http://harbinger:43011/UserService.svc?wsdl
and got pages load expected contents for both
Next I've decided to check if I can call the webservice from my machine, I've added the ServiceReference, executed a call to one of the methods and .... BOOM :
System.ServiceModel.CommunicationException was unhandled by user code
Message="An error occurred while trying to make a request to URI 'http://harbinger:43011/UserService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details."

See this blog post - I think that's the root cause of your problem:
Enabling cross-domain calls for Silverlight apps on self-hosted web services
or this one here:
WCF and Silverlight with cross-domain issue
Without any special policy files, you won't be able to call cross-domain in Silverlight.

Now, I have made sure that my server is using .NET 4. I have checked that the credentials are correct, many times. The app debugs fine. Just not after I've uploaded it.
What gives? I understand that it says "SecurityException and Access Denied, etc" - but what the hell does that actually mean when everything i've entered is OK?
You may want to check the Application on the web server. Make sure that the application pool and application are running under the correct permission levels for the type of application.
It can be a bit tricky, but typically you will get an error inside the application if there are bad credentials to the database or authentication of the user. If the application itself fails, there may be a permissions issue inside IIS.
Check the trust level for your application. Go to your application, and click on the .NET trust level, and change it to FULL
I am running an MVC web site on Windows Azure and using RavenDB embedded. If the web site is "cold" (unloaded from the Azure instance), I get the following error message on the first hit to the web site:

If I wait a minute or two, the web site comes up fine. So clearly this is a first-start issue. Anyone have any ideas how to resolve the problem?
My configuration:
MVC 4
.NET 4.5
RavenDB 2.0.2360
Update: The Azure team is looking at this as a possible defect with the Azure Websites. More updates as soon as I hear anything.
This was confirmed as a bug in Azure Websites, which has now been rolled out. I don't have any additional details, but the site now works (8/30/2013) and I have made no structural changes to the code.
Look at the event log, it will give you more info.
It looks like something is prevent proper write to the logs, check permissions, in particular, you may have CREATE_FILE permission, but not WRITE permission
I had a simple program , a asp.net website in which i added a webservice
One of the web methods accessed a CRM `
[WebMethod]
public bool RecordExists (String projectName)
{
var service = GetService("http://localhost/EventoCorp/");
Entity project = new Entity("new_project");
/*PROJECT DETAILS*/
project.Attributes["new_name"] = projectName;
var request = new RetrieveDuplicatesRequest
{
BusinessEntity = project,
MatchingEntityName = "new_project",
PagingInfo = new PagingInfo() { PageNumber = 1, Count = 50 }
};
Console.WriteLine("Retrieving duplicates");
var response = service.Execute(request);
EntityCollection collection = (EntityCollection)response.Results["DuplicateCollection"];
return collection.Entities.Count > 1 ? true : false;
}
When I press F5. the project runs fine . I invoke this record exists method , and it correctly brings data from the CRM 2011
However when i deploy this application on IIS 7.5 . I get greeted by this terribly uninformative exception
System.ServiceModel.FaultException: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs.

I am a CRM 2011 noob . No idea what is going on . Please help me
This exception happens in the client you use when trying to connect your web service. It says only that unhandled exception happened on server side, but has no information about exception. Also there is advice to enable IncludeExceptionDetailInFaults in order to pass to the client unhandled exception details. But there is also other way to see what is going on, it's attach to IIS process and debug your web service.
Also it would be better add exception handling to your code, because now code is completely unsafe. Different exceptions can happen when you are accessing CRM, like authentication exception etc. Also you can just get null instead of collection you suppose to be there.
When you deploying this code to IIS authentication issues are possible, since IIS is working under NETWORK SERVICE account. And in case if CRM uses Windows Authentication it's possible your request will not be authorized.
Ok, so I have this .NET 1.1 application (written by someone way back) which is like a document repository and it worked fine in the past. I suddenly get this error when trying to search for items/documents:
Page: /CPDEPforIT/SearchResults.aspx
Error:
System.Net.WebException: The request failed with HTTP status 401:

System.Web.UI.Page.ProcessRequestMain()
I don't remember any changes. Could this have been caused by something external to the application (IIS configurations/permissions, Server, Database)?
There are several things you need to verify.
Does the web service you are trying to access allow Anonymous Access? Authentication can be tricky for web-to-web calls
What is the web application running under, IWAM_xxx or IUSR_xxx? Or are you using an application pool running under a specific identity?
You may want to make sure your web application server's ASPNET or NETWORK SERVICE accounts can access your web service server.
If you want to get it working you could just provide an account for Anonymous Access...
Thanks!
I have also faced this type of issue before. In my case permission to the code folder works. Please check the folder permissions and then try with the IIS permissions.
