Samba mount problem

I have my computer connected to a Windows 2000 share via samba. I have problems, however, if that server is ever restarted. The mount point becomes inaccessable (i.e. 'ls' gives and error), and I cannot umount it ('server is busy' error). A umount -f does not work either. The only option I have found is to restart, which I hate to do. Any suggestions on how to avoid this, or at least how to get it re-mounted? I am mounting the server via /etc/fstab, with the following line: //xeon/c /xeon smbfs credentials=/etc/mypasswords,uid=1000,gid=100 0 0 (BTW, what does the '0 0' at the end do? I have never understood those numbers) Thanks, Kirk -- visit me at http://www.sparticus.us
