Optimized TCP/IP Registry Settings

	Note
	These settings are designed for a server with 768MB or more of RAM.

HKEY_LOCAL_MACHINE\SYSTEM\Services\Tcpip\Parameters\MaxUserPorts (DWORD)

This parameter should be set to 64511 (0xFBFF) (65535 minus 1024) to allow you to use the full tcp/ip port range.

HKEY_LOCAL_MACHINE\SYSTEM\Services\Tcpip\Parameters\MaxFreeTcbs (DWORD)

This parameter determines the number of TCP Control Blocks, which determines the allowed active number of connections. Each control block uses 1K total memory. This should be set to 65,535 (0x10000)

HKEY_LOCAL_MACHINE\SYSTEM\Services\Tcpip\Parameters\MaxFreeTWTcbs (DWORD)

This parameter determines the number of TCP Control Blocks allowed in the TIME_WAIT state. This should be set to 65,535 (0x10000)

HKEY_LOCAL_MACHINE\SYSTEM\Services\Tcpip\Parameters\MaxHashTableSize (DWORD)

This parameter determines the size of the hash table to lookup Tcbs. This can be set to the maximum value of 65,535 (0x10000) at a small expense of memory.
