The KB does document a hotfix, which did not work for this customer.

Changes:

HKLM\System\CCS\Services\LanmanServer\Parameters
CachedOpenLimit
DWORD: 0x0

HKLM\System\CCS\Services\LanmanWorkstation\Parameters
UtilizeNTCaching
DWORD: 0x0

HKLM\System\CCS\Services\RDR\Paremeters
UseWriteBehind
DWORD: 0x0

On the Windows 2000, sp2 File Server which hosts the FoxPro 6
Application we added the following registry keys:

HKLM\System\CCS\Services\LanmanServer\Parameters
EnableOpLocks
DWORD: 0x0

HKLM\System\CCS\Services\LanmanServer\Parameters
CachedOpenLimit
DWORD: 0x0
