Data type


Default value


0x5–0xFFFFFFFF ( seconds )

0xA ( 10 seconds )


Specifies the maximum acceptable age of an incoming mailslot message. If Net Logon receives a mailslot message that is older than the value of this entry, it ignores the message.

This limitation allows Net Logon to process recent messages efficiently. It assumes that the sender of the old message timed out and is no longer waiting for a response.

If this value is set too low, Net Logon might ignore important incoming mailslot messages. However, because Net Logon typically processes each mailslot message in a fraction of a second, the default value is usually optimal.
