打开。。就提示“无法打开登录所请求的数据库 "DesertEagle"。登录失败。用户 &dotCHINESE-39C27AD\ti&dot 登录失败。 ”要怎么改？

各位大侠，这段源码有两个数据库，ASPNETDB.MDF和DesertEagle.mdf，我在sql2005中附加了这两个数据库，打开主页的时候没问题，但用系统管理员登陆的时候报错。请指教，万分感谢<br/>其中，web.config中的设置是这样“&lt;add name=&quot;ConnectionString&quot; c providerName=&quot;System.Data.SqlClient&quot;/&gt;<br/>&nbsp;&nbsp;&lt;add name=&quot;DesertEagleConnectionString&quot;
