WCF托管在IIS中，连接到具有集成安全性的数据库时出现问题

在我的开发XP机器上，我有一个托管在IIS 5.1中的WCF服务。该服务无法连接到integrated security=true的sql server DB。当托管在控制台应用程序中时，同样的服务也可以正常工作。我已取消选中匿名访问并检查了IIS中的集成Windows身份验证

这些是我在Web.Config中的设置

 <connectionStrings>
 <add name="CADISEntities"  connectionString="metadata=res://*/UDI.CADISEntities.csdl|res://*/UDI.CADISEntities.ssdl|res://*/UDI.CADISEntities.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=DBSQLP404;Initial Catalog=CadisCustom;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
 </connectionStrings>

尝试通过谷歌搜索发现无法在IIS 5.1中设置应用程序池

任何修复此问题的建议都将不胜感激。

通过在连接字符串中提供完全限定的sql server名称来修复此问题。
