[Samba] Mounting smbfs

[Chuck Downing]

People,

When I try to mount a network share with the following command, using
kubuntu 5.10:

sudo mount -t smbfs -o
username=myusername,passwork=myuserpassword //esotericVAIO/Downloads /mnt/vaioDownloads

I get to following error message

mount: wrong fs type, bad option, bad superblock
on //esotericVAIO/Downloads,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so


I see the following error message in dmesg 

smbfs: mount_data version 1919251317 is not supported

What does the dmesg mean?

Thanks for your time.
