To change the time-out duration in the client-side during a UNC connection, specify the arbitrary time in KeepConn. Locate and then click the following key in the registry:

  • Location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters
  • Value: KeepConn
  • Data type: REG_DWORD
  • Range: 1 to 65535 (sec)
  • Default value: 600 sec = 10 mins
