    <p>I've been having endless woes trying to deploy an NServiceBus application that I had suspected were due to legacy code / application pool issues, so today I've set up a completely clean VM with Windows 7 x64 (SP1), installed Visual Studio 2008 and the latest <code>[NServiceBus 2.6.1504][1]</code> binaries, and I'm seeing exactly the same problem. I've unblocked the ZIP file, done the RunMeFirst.bat thing, and I'm using the .NET 3.5 AsyncPages example supplied with NServiceBus to reproduce the issue.</p> <p>Firstly, when I run both the server and the WebApplication1 example under Visual Studio, it works fine.</p> <p>The problem occurs when I try to run the WebApplication1 example under IIS. All I've done is to go into IIS Manager, right-click the default web site, and change the physical directory to the WebApplication1 folder in the NServiceBus distro.</p> <p>The default.aspx page loads OK and displays:</p> <blockquote> <p>Enter a number below and click "Go".</p> <p>If the number is even, the result will be "Fail", otherwise it will be "None". </p> </blockquote> <p>...but when I enter any kind of input and click "Go", it all goes wrong.</p> <p>The NServiceBus.host.exe process that's running the server produces the output:</p> <blockquote> <p>2011-09-19 00:31:23,623 [Worker.5] INFO NServiceBus.Unicast.UnicastBus [(null)] &lt;(null)> - Received message Messages.Command, Messages, Version=1.0.0.0, Cultur e=neutral, PublicKeyToken=null with ID 77ae75b7-ffad-4025-8163-13a83c60db91\41 f rom sender MyWebClient@WIN7-VM</p> <p>2011-09-19 00:31:23,632 [Worker.5] INFO NServiceBus.Unicast.UnicastBus [(null)] &lt;(null)> - Can't impersonate because no windows identity specified in incoming message. This is common in interop scenarios.</p> </blockquote> <p>(this is all in green which suggests it's not anything to worry about...?)</p> <p>Then I get two messages in the Windows event log:</p> <pre><code>Log Name: System Source: Microsoft-Windows-WAS Date: 19/09/2011 00:31:20 Event ID: 5011 Task Category: None Level: Warning Keywords: Classic User: N/A Computer: Win7-VM Description: A process serving application pool 'DefaultAppPool' suffered a fatal communication error with the Windows Process Activation Service. The process id was '3360'. The data field contains the error number. </code></pre> <p>There's then another identical message with a different process id, and then I get <code>The connection to **localhost** was interrupted</code>.</p> <p>Hitting "Refresh" just produces exactly the same behaviour - two NServiceBus log messages, two errors in the Windows event log, and then the "connection interrupted" message.</p> <p>This is a completely clean install, running binaries straight off the NServiceBus site, so I'm at a loss as to why it's not working - have I stumbled across an unsupported scenario or something? Any help much appreciated.</p>

    1. CONot sure if this is going to help, but I experienced what appear to be similar issues some time ago where WAS was logging exceptions, complaining that the error queue did not exist, even though it did. It didn't stop nsb from working, just made a lot of noise in the event log. After disabling the net.msmq listener adapter, the errors went away.

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
