用友u8软件客户通登陆报错

客户通登陆报错原因分析：通过检查：远程登录sql2005出错Error: An error has occurred while establishing a connection to the server. When connecting to sql server 2005, this failure may be caused by the fact that under the default settings sql Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)通过telnet IP 1433 发现服务器并没有监听在服务器上netstat -an查看果然如此检查server property中security中是否启用sql和windows混和登录和connection中是否allow remote connection检查configuration manager中是否启用了tcp ip和named pipe也可以在surface area 检查configuration中检查database engine的remote connection设置检查操作系统防火墙设置，打开1433端口但是问题还是依旧，最后发现在configuration manager中tcp/ip的property中IP Address：IP1设置的IP和port均没错，而IPALL中居然设置了Dynamic Port马上设置1433后，问题解决，难道安装完时就是这个作为默认值吗？ 问题解答：可先尝试一下修复,还是不行的话,是否可以备份数据,然后重装一次数据库和软件
