[Samba] Probs with smbfs

[michelld]

Hi all 
I am having trouble with my SMBFS and it is the following 
Every time I try to connect to other machine in my network, throught the command MOUNT, the folowing ERROR appears. I've already tried to see the manpage but i had not success. 
[root at backup_sp bin] mount -t smbfs //sarq/c /mnt/windows
Password: 
ERROR: smbfs filesystem not supported by the kernel 
Please refer to the smbnt (8) manual page 
smbmnt failed: 255 
I want to remember that service smb is running and last week, it was working properly. 
Please i need this help
I get very please about your attention. Thanks a lot
