JSI Tip 2145. Windows 2000 exhibits slow network throughput with some 3rd party programs?

When a 3rd party program performs a 'write only' open, or does one byte writes to a file, the Windows 2000 redirector can not use full caching.

Some programs may take an hour to complete in Windows 2000, but only a few seconds in Windows NT 4.0.

To enable the redirector to use full caching, use Regedt32 to navigate to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanWorkStation\Parameters

On the Edit menu, Add Value name EnableCachingOnWriteOnlyOpens, a type REG_DWORD value, and set the data value to 1.
