You experience poor performance when copying files on a TCP/IP Ethernet network from a MS-DOS client to a Windows 2000 computer?
The MS-DOS client attempts to fill the Windows 2000 receive buffer, but the MS-DOS real mode network adapter driver can't keep up, causing packets to be dropped.
The Windows 2000 computer uses a 17KB TCP receive window size by default.
To workaround this issue, you can set the Windows 2000 TcpWindowSize, a REG_DWORD data type, at
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip\Parameters, to 8192, using the Decimal Radix.
