This article describes the TCP/IP registry entries in the NetTrans subkey.

MORE INFORMATION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

The entries in this section must be added to the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\netTrans\000n

NOTE: Where n represents a specific TCP/IP-to-network adapter binding.

Value	Data type	Description
MaxMTU = 16-bit integer	DWORD	Specifies the maximum size datagram Internet Protocol (IP) that can pass to a media driver. Subnetwork Access Protocol (SNAP) and source routing header (if used on the media) are not included in this value. For example, on an Ethernet network, MaxMTU defaults to 1500. The actual value used is the minimum of the value specified with this parameter and the size reported by the media driver. The default value is the size reported by the media driver; an Ethernet network defaults to 1500 bytes and a Point-to-Point Protocol (PPP) dial-up connection defaults to 576 bytes.
ZeroBroadcast	String	If this parameter is set to 1, the IP uses zeros-broadcasts (0.0.0.0.) instead of ones-broadcasts (255.255.255.255.). Most systems use ones-broadcasts, but some systems derived from Berkeley Style Daemons (BSD) implementations use zeros-broadcasts. Interoperation does not work well on the same network for systems that use different broadcasts. Valid range 0 or 1 (false or true). The default value is 0.
