在安装好QC以后我在SQL 2000 里添加了个数据库是不是和这个有关系不知道怎么搞了！

dimang11

自己搞定了。。。安装完了QC 我更改了计算机的名字和IP地址，JBOSS就连接不到服务器了，因为JBOSS是通过计算机名来连接数据库主机的！
呵呵得到以下结论： 1.大家在安装QC前请把计算机的名称确定，不要随便更改！
                   2.如果你安装过程中SQL服务器的地址是填写的IP安装完成就不要修改IP地址！
以上都可能导致QC无法连接数据库服务器的原因！

cloud2000

安装QC的时候选择了域信息，现在域用户密码更改后，QC无法启动了！！请教各位高手如何解决？
