This server is a Samba server. This file in particular is being
written to via Samba by a Windows 2000 server over the network.

I would assume that's the file ACL:

hermes:/srv/samba/local/dumps/exchange# getfacl --numeric exchange-2000-UCWB-KVM-18.bkf
# file: exchange-2000-UCWB-KVM-18.bkf
# owner: 0
# group: 10140
user::rw-
user:10002:rwx                  #effective:rw-
group::r-x                      #effective:r--
group:10071:r-x                 #effective:r--
group:10136:rwx                 #effective:rw-
mask::rw-
other::---

Cheers,
Kevin.
