set new folder from win98 ws

1. We have chinese window 98 attach to a novell 5.1 sever. Everytime a user tries to create a new
directory (or folder) under his own home directory, the server will report an error. The
folder cannot be deleted or accessible. Probably
an international coding issue. Do I have to turn
on something on the server explicitly?

2. It seems that everytime when users tried to turn off their computer, it takes too much time to do so and on many occasion just hang on the ‘Turn off your machine’ screen instead of turning itself off. Could this be a novell problem?

Tks for your hand
