smbfs cause the stale file handle?
 

Hi,
I am running the redhat linux 9 and using the command as following to map Windows Storage 2003.
mount -t smbfs -o username=<username>,password=<passwd> //<ip address>/share /mntpoint

It is successful to map between linux and Windows but recently Windows happen the refuse connection on it because I check the linux host, the mounting still there and once I restart windows then I can read/write file to the directory without remount on linux site. Before I restart windows I can't ls the file in that directory, linux also display the error message as LS: Stale file handle. but mounting is still there by issueing command mount.

Could anybody tell me what is the happening? Please advise me........
