[CentOS] CentOS 4.5 - mounting remote windows fileserver using smb or cifs

Hi

I need to mount a windows share on a CentOS 4.5 box running stock kernel 
etc - I have tried using cifs and also smbfs

My fstab looks like

//share/name  	/mount/point	smbfs	username=user,password=password,uid=useridhere 0 0

or the same using cifs

When i try and mount that i get the following errors depending on the share type

smbfs: mount_data version 1919251317 is not supported

CIFS VFS: cifs_mount failed w/return code = -22

i would have thought that cifs was the way forward but any ideas? These use creds are being used on an ancient 7.3 box and they work fine

thanks
