[Samba] Windows 8 and roaming profiles hosted on Samba - NO ONE does this?

[Nick]

After searching Google for many days/weeks, I've discovered that apparently NO
ONE on the planet uses Windows 8 w/ roaming profiles and Samba!

Authentication server:
Windows Server 2003 R2 x64

File server:
FreeBSD 9.1
Samba 3.6.9

My configuration file is here:
http://xenomorph.net/linux/samba/configuration/sample/

Windows XP and Windows 7 work fine. Clean profile, imported profiles,
etc.With Windows 8, there seems to be some sort of profile corruption
when the
profile syncs. It always seems to trip up on files related to Internet
Explorer.

\Favorites, \Links, \IECompatCache, .url files, etc.

Event viewer is filled with stuff like this:

Windows cannot copy file
\\?\C:\Users\Derp\AppData\Roaming\Microsoft\Windows\IECompatCache\Low to
location
\\?\UNC\10.0.0.1\Share\Home\Derp\Profile.V2\AppData\Roaming\Microsoft\Windows\IECompatCache\Low.
This error may be caused by network problems or insufficient security
rights.

DETAIL - The parameter is incorrect.

Anyone have any suggestions, other than "don't use roaming profiles"???

Thanks,
