Red Hat Enterprise Linux 5.1 - 64bit

I am having some strange Samba/CIFS mounting issues.  I am trying to mount some Windows 2003 Server r2 file shares, and although I can mount them and 'ls' them, i cannot do anything with them.  The files are being seen as directories, I can CD to the files, and I can even CD to non-existant directories.  Can anyone look at the following info and help me out?

modinfo cifs |grep version
version:        1.48aRH
srcversion:     A7F70DFEAE2BF6EBBDE18A1

[shell]
[root@plus mnt]# ls -la /mnt/data/ 
total 34642
drwxrwxrwx 1 root root       0 Apr 24 08:34 .
drwxr-xr-x 5 root root    4096 Apr 21 15:17 ..
-rwxrwxrwx 1 root root  132508 Feb 21  2007 0220EM.CSV
-rwxrwxrwx 1 root root  147776 Jun 13  2007 061307.CSV
-rwxrwxrwx 1 root root  232448 Jun 13  2007 061307.xls

[root@plus mnt]# file data/0220EM.CSV
data/0220EM.CSV: directory
[/shell]

0220EM.CSV is NOT a directory but a file.  Additionally, if I CD to that directory and 'ls' there it gives me the same output as the /mnt/data/ directory does, meaning its recursing upon itself or something.

Additionally I can 'cd /mnt/data/fakedir/' and (1) it actually goes there, and (2) 'ls' gives the same output as 'ls /mnt/data/' :

[shell]
[root@plus mnt]# cd data/fakedir
[root@plus fakedir]# ls -la
total 34634

This is my current /etc/fstab:
