非常急的请教： quota设置错误

dailydai

我在redhat（文件服务器上）设置了quota,都成功了，但是客户端 不能login,返回的错误信息如下：
There was an error setting up inter-process communications for KDE.The message returned by the system was:
Could not read network connection list:
/home/wangd/Dcopserver_ws2__0
please check that the "dcopserver" program is running!
请问是什么问题，应该如何设置解决？？？谢谢！
但是用root可以login
