• Invalid message signature when running OpenId Provider on Cluster

  - by Garth

  Introduction We have an OpenID Provider which we created using the DotNetOpenAuth component. Everything works great when we run the provider on a single node, but when we move the provider to a load balanced cluster where multiple servers are handling requests for each session we get issue with the message signing as the DotNetOpenAuth component seems to be using something unique from each cluster node to create the signature. Exception DotNetOpenAuth.Messaging.Bindings.InvalidSignatureException: Message signature was incorrect. at DotNetOpenAuth.OpenId.ChannelElements.SigningBindingElement.ProcessIncomingMessage(IProtocolMessage message) in c:\BuildAgent\work\7ab20c0d948e028f\src\DotNetOpenAuth\OpenId\ChannelElements\SigningBindingElement.cs:line 139 at DotNetOpenAuth.Messaging.Channel.ProcessIncomingMessage(IProtocolMessage message) in c:\BuildAgent\work\7ab20c0d948e028f\src\DotNetOpenAuth\Messaging\Channel.cs:line 940 at DotNetOpenAuth.OpenId.ChannelElements.OpenIdChannel.ProcessIncomingMessage(IProtocolMessage message) in c:\BuildAgent\work\7ab20c0d948e028f\src\DotNetOpenAuth\OpenId\ChannelElements\OpenIdChannel.cs:line 172 at DotNetOpenAuth.Messaging.Channel.ReadFromRequest(HttpRequestInfo httpRequest) in c:\BuildAgent\work\7ab20c0d948e028f\src\DotNetOpenAuth\Messaging\Channel.cs:line 378 at DotNetOpenAuth.OpenId.RelyingParty.OpenIdRelyingParty.GetResponse(HttpRequestInfo httpRequestInfo) in c:\BuildAgent\work\7ab20c0d948e028f\src\DotNetOpenAuth\OpenId\RelyingParty\OpenIdRelyingParty.cs:line 493 Setup We have the machine config setup to use the same machine key on all cluster nodes and we have setup an out of process session with SQL Server. Question How do we configure the key used by DotNetOpenAuth to sign its messages so that the client will trust responses from all servers in the cluster during the same session?

• Zend Studio Debugger returns Application Error

  - by Keyne

  When I run debug for my public/index.php I got an application error as output. I've seen that it occurs at this line: foreach($feed->findFeedEntries($entriesLimit) as $entry) If I put a breakpoint before this, all works as expected, I mean, the error is after the line above. If I remove findFeedEntries() method, I can perform debugging without erros. To clarify, this method is in my row object as described bellow: This is the error <?php class Model_DbTable_FeedEntries extends Zf_Db_Table { public function fetchNewEntries($feed_id) { $Feeds = new Model_DbTable_Feeds(); $Feed = $Feeds->getById($feed_id); // ERROR IS HERE! The colum doesn't exists! // And this is only on zend-debugger!!! var_dump($Feed->link) // ... } } I'm completely lost about what's happening, once my application has no errors, the problem is with zend-debugger. The error is: An error occurred Application error Exception information: Message: Specified column "link" is not in the row Stack trace: #0 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\FeedEntries.php(75): Zend_Db_Table_Row_Abstract->__get('link') #1 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\FeedEntries.php(50): Model_DbTable_FeedEntries->fetchNewEntries('1') #2 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\Row\Feed.php(15): Model_DbTable_FeedEntries->getAllByFeedId('1', 1) #3 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\modules\default\controllers\IndexController.php(41): Model_DbTable_Row_Feed->findFeedEntries(1) #4 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Action.php(513): IndexController->indexAction() #5 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Dispatcher\Standard.php(289): Zend_Controller_Action->dispatch('indexAction') #6 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Front.php(954): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #7 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Application\Bootstrap\Bootstrap.php(97): Zend_Controller_Front->dispatch() #8 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Application.php(366): Zend_Application_Bootstrap_Bootstrap->run() #9 C:\Program Files\xampp\htdocs\desenvolvimentistas\public\index.php(54): Zend_Application->run() #10 C:\Users\RAPOSO\AppData\Local\Temp\dummy.php(1): include('C:\Program File...') #11 {main} I've notice that when I get the row object my colums names are not right.

• Outlook Addin in C# - How to add button/group in New Mail (next to signatures)

  - by MadBoy

  I'm having some trouble understanding Outlook terms (CommandBarPopup, CommandBarButton etc) like what is what in Outlook so please be patient. I would like to create couple of things: I would like to create new group (or just button but i read it's not possible to add a button to an existing group in ribbon) on new mail next to Signature/Add attachment in Message Ribbon. It would have to work the same way Signature works so when you press it it display couple of options. How can i create it? I would like to override a button "NEW" (where you can choose that you want to send new mail, make appointment or do other things) so that when you are in Main Window when you press the down arrow next to new button you could choose one of options i will add? Is this possible? How do I do it? I have some code that adds a menu in Main Window private void AddMenuBar() { try { //Define the existent Menu Bar menuBar = this.Application.ActiveExplorer().CommandBars.ActiveMenuBar; //Define the new Menu Bar into the old menu bar newMenuBar = (Office.CommandBarPopup) menuBar.Controls.Add(Office.MsoControlType.msoControlPopup, missing, missing, missing, false); //If I dont find the newMenuBar, I add it if (newMenuBar != null) { newMenuBar.Caption = "Test"; newMenuBar.Tag = menuTag; buttonOne = (Office.CommandBarButton) newMenuBar.Controls.Add(Office.MsoControlType.msoControlButton, missing, missing, 1, true); buttonOne.Style = Office.MsoButtonStyle.msoButtonIconAndCaption; buttonOne.Caption = "Test Button"; //This is the Icon near the Text buttonOne.FaceId = 610; buttonOne.Tag = "c123"; //Insert Here the Button1.Click event buttonOne.Click += new Office._CommandBarButtonEvents_ClickEventHandler(ButtonOneClick); newMenuBar.Visible = true; } } catch (Exception ex) { //This MessageBox is visible if there is an error System.Windows.Forms.MessageBox.Show("Error: " + ex.Message.ToString(), "Error Message Box", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); } } I would like to add submenu under the buttonOne so when i press it new submenus open up. How do I achieve that?

• cellForRowAtIndexPath not being called on tableView reloadData

  - by BotskoNet

  I have a UITableView on one view that loads in data at the start of the application, and then later when a user enters text into a box and hits a button, I re-query the database, re-populate the original NSMutableArray that stores the data for the table. All of that is working perfectly. In some logging statements I can tell that the array has the correct information, the numberOfRowsInSection method is returning the proper count, and is being called after the reload is called. However, the cellForRowAtIndexPath is never called the second time (after the reload) and the table data is never updated. I've spent hours searching the net and I've found nothing that helps. Can anyone help? All code is at: http://github.com/botskonet/inmyspot The specific reload is being called at: http://github.com/botskonet/inmyspot/blob/master/Classes/InMySpotViewController.m Roughly Line 94 From: http://github.com/botskonet/inmyspot/blob/master/Classes/PlateFormViewController.m Roughly line 101 A bit more info: once the new data has been added to the mutablearray, if I try to start scrolling the table, it eventually dies with: "Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (29) beyond bounds (29)'" Which I assume means the table cells can't find any data in the array to match the scroll position, which seems to be because the array has the new data, but the table doesn't.

• System.IO.FileLoadException

  - by Raj G

  Hi All, I have got this error when using Enterprise Library 3.1 May 2007 version. We are developing a product and have a common lib directory beneath the Subversion Trunk directory <\Trunk\Lib\ into which we put all the third party DLLs. Inside this we have Microsoft\EnterpriseLibrary\v3.1 in which we have copied all the dlls from \Program Files\Microsoft Enterprise Library May2007\bin. Everything was working properly until one of the developers installed the source code on this machine. There were some dlls copied at the end of the source code installation and once that was done, he is not able to run the project anymore. He always gets this error 'Microsoft.Practices.EnterpriseLibrary.Data, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)' What is the problem here? I thought that when the source code was installed it was just supposed to build everything and copy in the bin directory within the source code parent directory. Also we have copied the Dlls from Microsoft Enterprise Library May 2007\bin directory into our product development directory and references into our project with a copylocal flag set to true. Can anyone help me out here RK

• How do you clean Core Data generated models and code from a project?

  - by Hazmit

  I'm having an extremely annoying problem with Core Data in the iPhone SDK. I would say in general Core Data for the most part appears easy to use and nice to implement. I have a sqlite database that is being used as a read only reference to pull data elements out for an iPhone app. It would seem there are really mysterious issues relating to what seems to be migration of the database to the most recent versions of my schema. Why can't you just clean out your stored objects and models and let a project redo all of it when you compile next? You would think if you setup a stored object model there would be a way to just reset it and recompile. I've tried what feels like a thousand 'tips' that have been the results of hours of google searches and documentation prowling to figure out how to do this. My most recent error during compile time is below. 2010-04-07 18:23:51.891 PE[1962:207] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Can't merge models with two different entities named 'PElement'' All of this code has been working in the simulator and is only causing me troubles now because I made a change to the schema. I also have the database options for automatically migrating set as below. NSMutableDictionary *optionsDictionary = [NSMutableDictionary dictionary]; [optionsDictionary setObject:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption]; [optionsDictionary setObject:[NSNumber numberWithBool:YES] forKey:NSInferMappingModelAutomaticallyOption];

• Integration test failing through NUnit Gui/Console, but passes through TestDriven in IDE

  - by Cliff

  I am using NHibernate against an Oracle database with the NHibernate.Driver.OracleDataClientDriver driver class. I have an integration test that pulls back expected data properly when executed through the IDE using TestDriven.net. However, when I run the unit test through the NUnit GUI or Console, NHibernate throws an exception saying it cannot find the Oracle.DataAccess assembly. Obviously, this prevents me from running my integration tests as part of my CI process. NHibernate.HibernateException : The IDbCommand and IDbConnection implementation in the assembly Oracle.DataAccess could not be found. Ensure that the assembly Oracle.DataAccess is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly.* I have tried making the assembly available in two ways, by copying it into the bin\debug folder and by adding the element in the config file. Again, both methods work when executing through TestDriven in the IDE. Neither work when executing through NUnit GUI/Console. The NUnit Gui log displays the following message. 21:42:26,377 ERROR [TestRunnerThread] ReflectHelper [(null)]- Could not load type Oracle.DataAccess.Client.OracleConnection, Oracle.DataAccess. System.BadImageFormatException: Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.20, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies.

• Apache Mina Server Restart java.net.BindException: Address already in use

  - by Kosaki

  Hello, I have a rather annoying problem in my server application. I bind Apache Mina with the following code: acceptor.bind(new InetSocketAddress(PORT)); Where acceptor is an NioSocketAcceptor. Over a HTTP interface I can shutdown the server so I can restart it. Server.ioAcceptor.unbind(new InetSocketAddress(Server.PORT)); for(IoSession session: Server.ioAcceptor.getManagedSessions().values()){ if(session.isConnected() && !session.isClosing()){ session.close(false); } } Server.ioAcceptor.dispose(); Main.transport.stop(); Logger.getRootLogger().warn("System going down. Request from "+context.getRemoteAddress()); System.exit(10); This is the code I use to stop the Mina server. However if I try to start the server again in the next couple of minutes. (Somewhere between 5 minutes and 15 minutes) I get the following exception on start up: java.net.BindException: Address already in use I also tried a simple ioAcceptor.unbind() but there was no difference. The server runs on Centos 5 with OpenJDK. Apache Mina version is 2.0 RC1. Thank you in advance for any ideas on how to resolve this.

• Error editing a blob field in ArcGIS Engine

  - by Victor Grigoriu

  I have a GIS layer backed by a MSSQL db. The features on the layer have, say, one field of type esriFieldTypeString and one of type esriFieldTypeBlob. I can edit the string field just fine, but, when I try to edit a blob, StopEditOperation() throws a very generic exception (message: "Error HRESULT E_FAIL has been returned from a call to a COM component.", error code: -2147467259). I couldn't find anything related in the server log. Does anyone have any idea what's going on? IServerContext serverContext = GetServerContext(agsConn, serviceName); ILayer layer = GetILayer(layerName, serverContext); IWorkspace workspace = GetIWorkspace(layer); var feature = GetIFeature(objectId, workspace, layer); var workspaceEdit = (IWorkspaceEdit)workspace; workspaceEdit.StartEditing(false); workspaceEdit.StartEditOperation(); var index = feature.Fields.FindField(featureDetailName); IField field = feature.Fields.get_Field(index); byte[] byteArray = {1, 2, 3}; MemoryBlobStream blob = new MemoryBlobStream(); ((IMemoryBlobStreamVariant)blob).ImportFromVariant(byteArray); if (field.CheckValue(blob)) { feature.set_Value(index, blob); } feature.Store(); workspaceEdit.StopEditOperation(); workspaceEdit.StopEditing(true); serverContext.RemoveAll(); serverContext.ReleaseContext();

• Interoperability between Weblogic 10.3.1 and Oracle BPM 10.3.1

  - by alfredozn

  Hi, Im migrating an ALBPM 6.5 running on a WLS 10.0 to an Oracle BPM 10.3.1 running on WLS 10.3.1 I got some problems with the Oracle driver because the old driver (weblogic.jdbcx.oracle.OracleDataSource) was definitely removed from the server and is not longer supported. Instead I used the thin driver (oracle.jdbc.xa.OracleXADataSource), the database migration was executed succesfully but after that, when I try to deploy the engine ear in WebLogic I got exceptions asociated to the driver: [ (cont) ] Main: Caused by: weblogic.application.ModuleException: [HTTP:101216]Servlet: "engineStartup" failed to preload on startup in Web application: "/albpmServices/albpm_engine".

Any suggestions or similar experiences??

• When programatically creating a new IIS web site, how can I add it to an existing application pool?

  - by Ian Robinson

  I have successfully automated the process of creating a new IIS website, however the code I've written doesn't care about application pools, it just gets added to DefaultAppPool. However I'd like to add this newly created site to an existing application pool. Here is the code I'm using to create the new website. var w3Svc = new DirectoryEntry(string.Format("IIS://{0}/w3svc", webserver)); var newsite = new object[] { serverComment, new object[] { serverBindings }, homeDirectory }; var websiteId = w3Svc.Invoke("CreateNewSite", newsite); site.Invoke("Start", null); site.CommitChanges(); <update Although this is not directly related to the question, here are some sample values being used above. This might help someone understand exactly what the code above is doing more easily. webServer: "localhost" serverComment: "testing.dev" serverBindings: ":80:testing.dev" homeDirectory: "c:\inetpub\wwwroot\testing\" </update If I know the name of the application pool that I'd like this web site to be in, how can I find it and add this site to it? <update 2 I've added the following based on Mark's answer below. var appPool = new DirectoryEntry(string.Format("IIS://{0}/w3svc/AppPools/{1}", webServer, appPoolName)); site.Properties["AppPoolId"].Value = appPool; I seem to have moved passed the "RPC" error message I was initially receiving. Now this is the error message I'm receiving: Error: System.Runtime.InteropServices.COMException (0x8000500C): Exception from HRESULT: 0x8000500C at System.DirectoryServices.Interop.UnsafeNativeMethods.IAds.PutEx(Int32 lnControlCode, String bstrName, Object vProp) at System.DirectoryServices.PropertyValueCollection.set_Value(Object value) at ProvisionIISWebsite.Query.CreateWebsite(String webServer, String serverComment, String serverBindings, String homeDirectory, String appPoolName) in C:\Users\irobinson\My Projects\ProvisionIISWebsite\Query.cs:line 104 at ProvisionIISWebsite.Query.Handle_GetData(EngineBase& caller, Boolean isSubQuery, String query, String filterField, String filterText, Debugger& debugWriter, Boolean isRendered, Int32 timeout, String customConnection) in C:\Users\irobinson\My Projects\ProvisionIISWebsite\Query.cs:line 36 </update 2

• Entity Framework, Foreign Keys and EntityKeys

  - by Greg

  I've got a problem with the Entity Framework and the ForeignKeys. I've got a table "BC_Message_Assets" which has 3 FK's (MessageId, AssetId and StatusId). I create my "MessageAsset" like this MessageAsset messageAsset = new MessageAsset(); messageAsset.MessageStatusReference.EntityKey = new EntityKey("MyEntities.MessageStatusSet", "Id", 1); messageAsset.AssetReference.EntityKey = new EntityKey("MyEntities.AssetSet", "Id", 1); messageAsset.MessageReference.EntityKey = new EntityKey("MyEntities.MessageSet", "Id", messageId); context.AddToMessageAssetSet(messageAsset); context.SaveChanges(); But I got the following exception : The INSERT statement conflicted with the FOREIGN KEY constraint \"FK_BC_Message_Assets_BC_Assets\". The conflict occurred in database \"Test\", table \"dbo.BC_Assets\", column 'Id'.\r\nThe statement has been terminated. When I look at the query, I notice that the parameter value for AssetId is "0" despite that I provided "1" to the EntityKey. Here's the generated query : exec sp_executesql N'insert [dbo].[BC_Message_Assets]([MessageId], [AssetId], [CompletionTime], [StatusId]) values (@0, @1, null, @2) ',N'@0 int,@1 int,@2 int',@0=47,@1=0,@2=1 I can't explain what happens. I hardcoded "1" in the EntityKey and I received "0" in the query ?

• InstallShield 2010 with license - no license for automatic build system (CI) as Windows service

  - by Gilad

  I really need help here. We are using CI build-process (Hudson) as an automated build system using Msbuild. The CI run in Apache Tomcat 6 that run under the credentials of a domain user (not a local Windows user ). Every time the CI try to build an InstallShield project (using isproj files) we get a license error message: " C:\Program Files\MSBuild\InstallShield\2010\InstallShield.targets(62,3): error : -7159: The product license has expired or has not yet been initialized. You must launch the IDE to configure the product license in order to proceed. C:\Program Files\MSBuild\InstallShield\2010\InstallShield.targets(62,3): error : Exception Caught". If I log in to the same machine with the same domain user credentials and build the InstallShield project there is a license and it is working well. Adding the user to the local Users group doesn't help (no license). Adding the user to the local Administrators group helps and it is working. We do not want the user to be in the local Administrators group - for various reasons. What do I need to do to make it work? Do I need to add permissions to the use? Help will be highly appreciated.

• How can I run BitchX when I don't have ssh or shell access?

  - by Christopher

  I just installed an IRC bot, B****X (Don't ask, I don't know - the real name is not censored). I did all of the configuration and chmod'ed the pl files to 755, but running it won't work. My host does not allow SSH/Shell (which is how the documentation says to runs he script), but just going to the URL usually works because of this. However, I get a 500 (Internal Server Error) error. I have logged errors: Possible unintended interpolation of @moz in string at ./bitch.conf line 78 (#1) (W ambiguous) You said something like `@foo' in a double-quoted string but there was no array @foo in scope at the time. If you wanted a literal @foo, then write it as \@foo; otherwise find out what happened to the array you apparently lost track of.

• Improving long-polling Ajax performance

  - by Bears will eat you

  I'm writing a webapp (Firefox-compatible only) which uses long polling (via jQuery's ajax abilities) to send more-or-less constant updates from the server to the client. I'm concerned about the effects of leaving this running for long periods of time, say, all day or overnight. The basic code skeleton is this: function processResults(xml) { // do stuff with the xml from the server } function fetch() { setTimeout(function () { $.ajax({ type: 'GET', url: 'foo/bar/baz', dataType: 'xml', success: function (xml) { processResults(xml); fetch(); }, error: function (xhr, type, exception) { if (xhr.status === 0) { console.log('XMLHttpRequest cancelled'); } else { console.debug(xhr); fetch(); } } }); }, 500); } (The half-second "sleep" is so that the client doesn't hammer the server if the updates are coming back to the client quickly - which they usually are.) After leaving this running overnight, it tends to make Firefox crawl. I'd been thinking that this could be partially caused by a large stack depth since I've basically written an infinitely recursive function. However, if I use Firebug and throw a breakpoint into fetch, it looks like this is not the case. The stack that Firebug shows me is only about 4 or 5 frames deep, even after an hour. One of the solutions I'm considering is changing my recursive function to an iterative one, but I can't figure out how I would insert the delay in between Ajax requests without spinning. I've looked at the JS 1.7 "yield" keyword but I can't quite wrap my head around it, to figure out if it's what I need here. Is the best solution just to do a hard refresh on the page periodically, say, once every hour? Is there a better/leaner long-polling design pattern that won't put a hurt on the browser even after running for 8 or 12 hours? Or should I just skip the long polling altogether and use a different "constant update" pattern since I usually know how frequently the server will have a response for me?

• Unit testing Monorail's RenderText method

  - by MikeWyatt

  I'm doing some maintenance on an older web application written in Monorail v1.0.3. I want to unit test an action that uses RenderText(). How do I extract the content in my test? Reading from controller.Response.OutputStream doesn't work, since the response stream is either not setup properly in PrepareController(), or is closed in RenderText(). Example Action public DeleteFoo( int id ) { var success= false; var foo = Service.Get<Foo>( id ); if( foo != null && CurrentUser.IsInRole( "CanDeleteFoo" ) ) { Service.Delete<Foo>( id ); success = true; } CancelView(); RenderText( "{ success: " + success + " }" ); } Example Test (using Moq) [Test] public void DeleteFoo() { var controller = new FooController (); PrepareController ( controller ); var foo = new Foo { Id = 123 }; var mockService = new Mock < Service > (); mockService.Setup ( s => s.Get<Foo> ( foo.Id ) ).Returns ( foo ); controller.Service = mockService.Object; controller.DeleteTicket ( foo.Id ); mockService.Verify ( s => s.Delete<Foo> ( foo.Id ) ); Assert.AreEqual ( "{success:true}", GetResponse ( Response ) ); } // response.OutputStream.Seek throws an "System.ObjectDisposedException: Cannot access a closed Stream." exception private static string GetResponse( IResponse response ) { response.OutputStream.Seek ( 0, SeekOrigin.Begin ); var buffer = new byte[response.OutputStream.Length]; response.OutputStream.Read ( buffer, 0, buffer.Length ); return Encoding.ASCII.GetString ( buffer ); }

• WCF Security in a Windows Service

  - by Alphonso

  I have a WCF service which can run as Console App and a Windows Service. I have recently copied the console app up to a W2K3 server with the following security settings: <wsHttpBinding> <binding name="ServiceBinding_Security" transactionFlow="true" > <security mode="TransportWithMessageCredential" > <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> <serviceCredentials> <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="Common.CustomUserNameValidator, Common" /> </serviceCredentials> Security works fine with no problems. I have exactly the same code, but running in a windows service and I get the following error when I try to call any of the methods from a client: System.ServiceModel.Security.MessageSecurityException was unhandled Message="An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail." Source="mscorlib" StackTrace: Server stack trace: at System.ServiceModel.Channels.SecurityChannelFactory`1.SecurityRequestChannel.ProcessReply(Message reply, SecurityProtocolCorrelationState correlationState, TimeSpan timeout) ...... (lots of stacktrace info - not very useful) InnerException: System.ServiceModel.FaultException Message="An error occurred when verifying security for the message." The exception tells me nothing. I'm assuming that it has something to do with acces to system resources from the Windows Service. I've tried running it under the same account as the console app, but no luck. Does anyone have any ideas?
