How can I modify the Server Message Block (SMB) connection failure time under Windows NT 4.0?

A. If a server can't accept a new SMB session request from a client because of insufficient resources or server problem, the server will send a negative response to the client after 10 seconds. To modify this response time, perform the following steps on the server:

  1. Start a registry editor (e.g., regedit.exe).
  2. Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Rdr\Parameters registry subkey.
  3. Double-click the FailedConnectTimeout value (of type DWORD), enter the number of seconds you want to use for the timeout period, then click OK.
  4. Restart the server.

For Windows 2000 and later, a hardcoded value of 10 seconds is used.
