Dear friends:
the NFS client changed the owner of the sharing file directory. The owner of directory should be “stu001” , but in the clent machine, it is “1006”. I can not change the ower even with root. The other ten client machine works correctly.
How to resovle this problems.

I guess that on the server UID 1006 is user stu001. Same on most of the client systems. But on that one client system UID 1006 has no entry in /etc/passwd (user stu006 does not exist, or is the user name of another UID).

You conclusion that the owner changed is not true. The owner is 1006. Which happens to be stu001 on most systems, but not on that one you complain about.
