*不能连接上远程数据库*解决方案

******不能连接上远程数据库**********
网站一直允许正常，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
