运行WCF服务为特定的用户时，元数据错误 [英] Metadata error when running WCF service as particular user

问题描述

我已经部署了一个WCF服务，当应用程序池运行作为一个特定的域用户的伟大工程，但是当我更改应用程序池作为一个不同的用户身份运行，我得到一个XPATH错误，我的服务甚至没有回报元数据。我很困惑 - 我的新用户有权所有服务文件（包括配置文件），正常运行作为一个应用程序池的身份，和数据库的权限并不重要，因为我不能连拉了一个合同清单

任何人都可以揭示出这个一些启示？当我尝试使用WCF测试客户端来连接我连接我得到了错误的文本。更改应用程序池作为第一个用户运行和测试客户端将一份合同清单，我可以在所有调用的方法没有任何问题。请救救我！

解决方案

也有类似的问题。我通过授予IIS_WPG组全面进入到c固定它：\ WINDOWS \ TEMP文件夹中的服务器上

I have deployed a WCF service that works great when the application pool runs as a particular domain user, but when I change the application pool to run as a different user, I get an XPATH error and my service doesn't even return metadata. I'm perplexed - my new user has permissions to all the service files (including config files), runs fine as an app pool identity, and database permissions don't matter because I can't even pull up a contract list.

Can anybody shed some light on this? I've attached the text of the error I get when I try to connect using the WCF Test Client. Changing the app pool to run as the first user and the test client pulls up a contract list, and I can call a method without any issues at all. Please save me!

解决方案

Had a similar issue. I fixed it by granting the IIS_WPG group full access to the c:\windows\temp folder on the server.
