[Samba] strange permission denied problem

I built an embedded box which uses mount.cifs to mount network
shares. I've shipped several of these and all are working fine except
for one, which gives me permission denied on certain files:
root at Mnemosyne:~/mnt/bgrp1/c/Ballance Group Folders/Scully/Client
Photos-Scully# cat "Office Pics 002.jpg" > /dev/null
cat: Office Pics 002.jpg: Permission denied
root at Mnemosyne:~/mnt/bgrp1/c/Ballance Group Folders/Scully/Client
Photos-Scully# cat "Iron & Concrete Table.jpg" > /dev/null
root at Mnemosyne:~/mnt/bgrp1/c/Ballance Group Folders/Scully/Client
Photos-Scully#
So only the Office Pics file gets a permission denied.
root at Mnemosyne:~/mnt/bgrp1/c/Ballance Group Folders/Scully/Client
Photos-Scully# ls -al
dr-xr-x--- 1 root root 0 Mar 28 14:22 .
dr-xr-x--- 1 root root 0 Mar 27 17:35 ..
-r--r----- 1 root root 113826 Mar 3 16:26 Iron & Concrete
Table.jpg
-r--r----- 1 root root 744886 Feb 21 16:14 Nightstands.jpg

-r--r----- 1 root root 90670 Mar 28 14:22 Office Pics 002.jpg
cat /proc/mounts says:
//bgrp1/c /tmp/mnt/bgrp1/c cifs
ro,mand,nodiratime,unc=\\bgrp1\c,username=root,domain=,rsize=4100,wsize=4100
0 0
and the mount line itself is
mount.cifs "//$server/$wshare" /tmp/mnt/$server/$lshare -o
ip=$target,guest,ro,file_mode=0440,dir_mode=0550
I can't for the life of me figure out why some files give me a
permission denied. I have no physical access to the problem box; here's
what I know:
------------------------------------------+
Looking up status of 192.168.0.2
BGRP1 <00> - B <ACTIVE>
MSHOME <00> - <GROUP> B <ACTIVE>
BGRP1 <20> - B <ACTIVE>
MSHOME <1e> - <GROUP> B <ACTIVE>
MSHOME <1d> - B <ACTIVE>
..__MSBROWSE__. <01> - <GROUP> B <ACTIVE>
MAC Address = 00-19-DB-A6-43-23

How do I go about diagnosing this?
Thanks,
