Problem Mounting CIFS

[Nathaniel Hall]

I am trying to mount a Windows file share in Fedora Core 3 and 4.  The 
command I am using is:

 >> mount -t cifs -o username=username,password=password //server/share 
/mountpoint

When I run this command I get this error to the screen:

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

and this error in dmesg:

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

I have tried this on two different Fedora boxes mounting to two 
different Windows boxes.  Does anybody have any ideas?
