When a network drive (net use) is disconnected, Windows Explorer keeps searching it for 30 seconds. Is there some registry setting or something to reduce this to maybe 5 seconds?

Just to clarify, I'm not asking about network drives that are automatically disconnected by the local Windows after a certain period of time, but about drives that are actually unavailable, e. g. because the target computer is turned off.

In Windows 7 and Vista mapped network drives will disconnect themselves after a time and show a red cross on the drive icon. You will still be able to click on the drive and see/use the contents but applications that require a network drive will see them as disconnected and will not see files. If you try to disconnect the drive, it will still sit there saying 'Disconnected Network Drive' - the only solution is to reboot. This is because there is a default disconnect time for inactive network connections. To correct this and turn the autodisconnect off do the following:

  1. Open the command prompt as Administrator. To do this, either:

    • go to Start → All Programs → Accessories, right-click "Command Prompt" and select "Start as Administrator", or

    • type cmd into the search box and press Ctrl+Shift+Enter

  2. In the command prompty, type the following:

    net config server /autodisconnect:-1
  3. Press Enter

  4. Reboot computer

Your mapped network drives should now stay connected - this is a permanent fix.

Fixing this issue on the client side involves the registry change. Simply open regedit and locate KeepConn key in the registry:


If not exist, create it in Reg_Dword, and set the time in seconds. For example, I set it as one day to keep the connection live.
