This article documents the Windows NT and Windows 2000 local area network (LAN)-related Autodisconnect parameter.
Windows NT and Windows 2000 use two different Autodisconnect parameters; one for disconnecting Remote Access Service (RAS) connections and another for disconnecting LAN connections. The RAS Autodisconnect parameter is documented in the Microsoft Knowledge Base article Q153944, but the LAN version is undocumented. The only published reference to this Autodisconnect is in the Windows NT Resource Kit NT Registry Entries help file, in an overview of entries for the LanmanServer Parameters section.
You can find the LAN Autodisconnect parameter in the registry under the subtree HKEY_LOCAL_MACHINE under the subkey:
\System\CurrentControlSet\Services\LanmanServer\ParametersNOTE: The preceding entry must be located on the computer that has the share or shares.
The purpose is to disconnect idle sessions after a set number of minutes. The number of minutes can be set at a command prompt using the net config server command.
For example, to set the Autodisconnect value to 30 minutes, you would run the following command line:
net config server /autodisconnect:30The valid value range is -1 to 65535 minutes at the command line. To disable Autodisconnect set it to -1.
Setting Autodisconnect to 0 does not turn it off and results in very fast disconnects, within a few seconds of idle time. (However, the RAS Autodisconnect parameter is turned off if you set it to a value of 0.)
