错误详情如下。 是我错过了什么？ 需要你的专业知识来指导这个错误。解决方案 由于你的web应用程序无法连接的异常SQLSERVER实例。以下是解决问题的方法： 1. 检查您的服务是否正在运行 转到所有程序> Microsoft SQL Server 2012>配置工具> SQL Server配置管理器> SQL Server服务 检查以确保SQL Server服务状态正在运行。 或 打开运行命令控制台（Windows + R），然后键入 services.msc 。您将系统中的所有服务和检查SqlServer（Sqlexpress）服务正在运行模式。 2. 确保您的数据库引擎配置为接受远程连接 开始>所有程序> SQL Server 2005>配置工具> SQL Server表面区域配置 单击服务和连接的表面区域配置 选择出现问题的实例>数据库引擎>远程连接 启用本地和远程连接 在运行命令窗口中使用 services.msc 重新启动实例（在＃中讨论） 1） 3. 在SQL Server配置中启用TCP / IP 转到所有程序>> Microsoft SQL Server 2012>配置工具>> SQL Server配置管理器>>选择TCP / IP 右键单击TCP / IP>>单击启用 然后在运行命令窗口中使用 services.msc 重新启动sqlserver服务（在＃1中讨论） ） 最后你需要检查它可能是服务器防火墙设置，因为有时防火墙会阻止来自其他服务器的传入请求。并检查您是否提供正确的连接字符串意味着用户名，密码，服务器等。 运行此更新： asp_net_regiis .EXE Hello,For my organization, I have developed database web application

Following are options to resolve the problem:1. Check if your service is running upGo to All Programs > Microsoft SQL Server 2012 > Configuration Tools > SQL Server Configuration Manager > SQL Server ServicesCheck to make sure SQL Server service status is Running.orOpen run command console(Windows + R) then type services.msc. You will all services in your system and check SqlServer (Sqlexpress) service is running mode.2. Make sure your database engine is configured to accept remote connectionsStart > All Programs > SQL Server 2005 > Configuration Tools > SQL Server Surface Area ConfigurationClick on Surface Area Configuration for Services and ConnectionsSelect the instance that is having a problem > Database Engine > Remote ConnectionsEnable local and remote connectionsRestart instance using services.msc in run command window(discussed in #1)3. Enable TCP/IP in SQL Server ConfigurationGo to All Programs >> Microsoft SQL Server 2012 > Configuration Tools >> SQL Server Configuration Manager >> Select TCP/IPRight Click on TCP/IP >> Click on EnableThen restart the sqlserver service using services.msc in run command window(discussed in #1)Lastly you need to check that it might be server firewall setting because sometimes firewall blocks incoming request from other servers. And also check you are providing correct connection string means username, password, server etc..run this update:asp_net_regiis.exe 这篇关于'/'应用程序中的服务器错误。访问被拒绝，[win32exception（0x80004005）：访问被拒绝]的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
