Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. 解决办法

今天下载了最新的CS2008 试了试，安装完数据库后出现这个问题：

 

Specific Error Message:

Unable to open connection to data provider.

Cannot open database "CommunityServer" requested by the login. The login failed. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.

 

解决办法：在数据库连接字符串后加上：(集成安全)

Integrated Security=false；就可以了.
