[Samba] smbmount

[PG]

Hi, 
    I'm using smbmount to mount winme boxes to my redhat 7.3 to perform
daily backup with taper. Everything is working well except when one of the
winme boxes crashed (you know it happens frequently), the smbmount locked
the "mount" process. I can't smbumount, or kill the process at all. All I
can do is restart the whole server.
Is is possible to :
1. detect whether there is a crash in the win boxes?
2. how can I release the mounting?
