这个是什么原因造成的。是数据库转换上出的问题么？？
在server 2003+sqlserver 2000上出现的这个问题，然后不可能在服务器上添加用户。因为安全性的问题。数据库用户更改也不行，更改链接字符串应该更改那里？

web.config
或者
你写连接字符串的地方

[人间太皮]

1楼很全了。
web.config中改如下节点：
<appSettings>
<add key="ConnectionString" value="server=192.168.1.10;database=PostGraduateStuUser;uid=sa;pwd=123456"/>
</appSettings>


使用sqlConnection 的地方
SqlConnection con = new SqlConnection("server=192.168.1.10;database=PostGraduateStuUser;uid=sa;pwd=123456");

[Lovely_baby]

很明显的数据库连接的问题？
检查一下连接字符串.....

[wullhien]

最关键的问题是。
<connectionStrings>
<add name="ictcomConnectionString" connectionString="Data Source=203.171.228.26,1433;Initial Catalog=ictcom;User ID=sa;Password=123456;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>

真不知道是那里错了。。好像没有什么错的地方啊。。崩溃啊！！

NT AUTHORITY\NETWORK SERVICE

登陆失败

安全性--》登录名-》右键 新建登录名-》在常规选项卡》高级 -》立即查找 newwork service 双击添加

[wullhien]

求救，求救！！！有没有那位大哥能教我更改链接字符串的方法解决这个问题？

[vrhero]

删除Integrated Security=True或改成Integrated Security=False...

5楼的方法是饮鸩止渴，不要用...

[wullhien]

试过了诶。。不行的说。。我都被这问题困扰了好几天了。5楼的方法我知道。。牵扯到了服务器安全性的问题。我快愁死了。。两天头发白了好几十根了！！！崩溃啊！！
