Figured out the issue...

After comparing a good vs bad file copy in wireshark for a while, I
have found where it goes wrong. On the good copy I see an "NT Create
AndX Request" with a response that says it created the file. On the
bad copy it instead does a "NT Trans Request, NT CREATE" with an
additional "NT CREATE data" that has the SELinux context in it.
Comparing the old vs new smb.conf man page it looks like "ea support"
in the older samba version was default to no, while it is default to
yes in the newer samba version. Windows is some how storing those
extended attributes, and fails when trying to transfer a file with the
selinux extended attribute.

Setting "ea support = no" fixed the issue.
