******不能连接上远程数据库**********
网站一直运行正常，但是突然一天早上打开页面出现这个错误，

A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 0 -
An existing connection was forcibly closed by the remote host.)


水能帮我分析分析甚么原因，
我用的是asp.net 2.0 + Sql2005


[解决办法]
SQL Server 外围应用配置器—服务和连接外围配置—database englie—远程连接—启用(远程连接的TCP/IP和named pipes)
SQL Server Configuration Manager—SQL2005网络配置—启用TCP/IP和named pipes
