blocks|key|246042|text|您是否在此区域使用任何ODBC或其他组件，而您在其他任何地方都不使用？当我在64位模式下运行应用程序池时，我遇到过这个错误(或者类似的错误，我想不起来了)，底层调用是引用32位的“something”。您可以尝试在应用程序池设置中启用32位应用程序，看看它是否会影响结果。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|246043|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Are you using any ODBC or other components in this area that you are not anywhere else? I have experienced this error (or one similar, can't remember off the top of my head) when running the app pool in 64bit mode and the underlying calls are referencing at 32bit 'something'. You could try enabling 32bit applications in the application pool settings to see if it affects the outcome.

blocks|key|3139637|text|我想通了。这是由于SQL+Reporting+services在http.sys中保留了http://%2B:80/Reports+url。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3139638|我实际上并没有安装报告服务，但它显然仍然保留了url。|3139639|我用下面的命令修复了它：|3139640|netsh+http+delete+urlacl+url=http://%2B:80/Reports|code-block|syntax|javascript|3139641|entityMap|0|LINK|mutability|MUTABLE|url|http://%2B/Reports^0|18|J|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|Z|8|@]|9|@]|C|$]]|$1|H|3|I|5|J|7|10|8|@]|9|@]|C|$K|L]]|$1|M|3|-4|5|6|7|11|8|@]|9|@]|C|$]]]|N|$O|$5|P|Q|R|C|$S|T]]]]

I figured it out. It was due to SQL Reporting services having reserved the <a href="http://+:80/Reports">http://+:80/Reports</a> url in http.sys.

I didn't actually have reporting services installed, but it apparently still reserved the url.

I fixed it with the following command:

<pre><code>netsh http delete urlacl url=http://+:80/Reports
</code></pre>

blocks|key|3139661|text|检查运行池所使用的帐户/+IIS+->应用程序池->高级设置->进程模型->标识。我更改了我的密码，没有得到一个无效密码的日志，而是汇编加载失败，这反过来导致应用程序池关闭，并向用户提供"503服务不可用“。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3139662|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Check the account / IIS -> Application Pool -> Advanced Settings -> Process Model -> Identity under which your pool is running. I had my password changed, and didn't get a log on invalid password, but rather assemlby load failure, which in turn caused the app pool to be shut off, and the "503 Service Unavailable" was given to the user.

blocks|key|250997|text|另一个解决方案是，我的http://ApplicationURL/Reports也有同样的问题|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|250998|是的，SSRS是问题所在。|250999|一个更好的解决方案是|251000|本地服务的|251001|OpenReporting服务配置Manager.|ordered-list-item|251002|Connect通常是COMPUTERNAME\MSSQLSERVER|251003|Go+to“报表管理器URL”选项|251004|使用其他名称而不是报表修改您的虚拟目录。|251005|251006|请记住，使用此更改后，SSRS的报告将使用您定义的名称。|251007|卡洛斯|251008|entityMap|0|LINK|mutability|MUTABLE|url|http://applicationurl/^0|X|7|B|M|0|0|0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|17|8|@$9|18|A|19|B|C]]|D|@$9|1A|A|1B|1|1C]]|E|$]]|$1|F|3|G|5|6|7|1D|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|1E|8|@]|D|@]|E|$]]|$1|J|3|K|5|6|7|1F|8|@]|D|@]|E|$]]|$1|L|3|M|5|N|7|1G|8|@]|D|@]|E|$]]|$1|O|3|P|5|N|7|1H|8|@]|D|@]|E|$]]|$1|Q|3|R|5|N|7|1I|8|@]|D|@]|E|$]]|$1|S|3|T|5|N|7|1J|8|@]|D|@]|E|$]]|$1|U|3|-4|5|6|7|1K|8|@]|D|@]|E|$]]|$1|V|3|W|5|6|7|1L|8|@]|D|@]|E|$]]|$1|X|3|Y|5|6|7|1M|8|@]|D|@]|E|$]]|$1|Z|3|-4|5|6|7|1N|8|@]|D|@]|E|$]]]|10|$11|$5|12|13|14|E|$15|16]]]]

Another solution is, I had the same problem with my <a href="http://ApplicationURL/" rel="nofollow noreferrer">http://ApplicationURL/</a>Reports

And yes the SSRS was the issue. 

A better solution for this one is

<ol>
<li>OpenReporting Services Configuration Manager.</li>
<li>Connect to your local service usually COMPUTERNAME\MSSQLSERVER</li>
<li>Go to "Report Manager URL" Option</li>
<li>Modify your virtual directory with another name instead of Reports.</li>
</ol>

Just remember with this change you reports for SSRS will be in the name that you defined.

As mentioned before it is related to SQL Reporting services
You can follow this approach to fix this problem:

Log on to the server that hosts SSRS.

Go to Start > Programs > SQL Server 2008 R2 > Configuration Tools > Reporting Services Configuration Manager

Connect to the server in question (usually your local server)

Go to the Web Service URL section

Change the TCP port to an open port other than port 80 (81 happened to work on my server) and hit Apply

Go to the Report Manager URL section

Click Advanced

Click the entry with a TCP port of 80 and then click the Edit button.

Change the TCP Port entry to the same thing you changed it to in the Web Service URL section previously and Click OK.

Click OK again.

We're switching our MVC3 application from IIS 6 to 7.5. I'm working on setting up my local development environment on Windows 7. The app works fine for the most part, but I just discovered that ONE out of the many different MVC Areas I have doesn't work.

When I try hit an action under this area, I get a 503 Service Unavailable error back. This does not happen anywhere else in my application.

<ul>
<li>There is only one application pool for the whole website. </li>
<li>MVC 3</li>
<li>.Net 4.0</li>
<li>64 bit</li>
<li>Failed request tracing doesn't see these requests.</li>
<li>There is nothing relevant in the Windows application or system logs.</li>
<li>The area works fine under visual studio 2010 cassini, problem happens when I run it under local iis 7.5 (not express)</li>
<li>App pool isn't crashing or otherwise stopped</li>
<li>There's nothing in my ELMAH log</li>
<li>Everyone full control on entire tree in the filesystem security </li>
<li>The url is <a href="http://localhost/reports" rel="noreferrer">http://localhost/reports</a></li>
</ul>

I'm totally stumped. I can't find any evidence that IIS is even getting the request at all. Is there some other log file beside the ones I listed?

[Update]
Is there any way to view the http.sys URL reservations? I have found some talk about SQL Reporting services calling dibs on /Reports url.

What might cause a 503 Service Unavailable for reports area of an asp.net mvc3 application?
