In Microsoft Windows 2000, when you try to remove or to update a network driver interface specification (NDIS) intermediate driver that requires a Notify Object DLL, you may experience all the following symptoms:
  • If you open the Properties dialog box of the device in the Network and Dial-up Connections Control Panel item, and then click Uninstall to remove that device, the device driver appears to be removed successfully. However, the device driver's .dll file remains in the %WINDIR%\System32 folder.
  • If you try to delete the driver's .dll file from the %WINDIR%\System32 folder, you receive the following error message:
    Cannot delete filename: Access is denied. The source file may be in use.
  • If you try to install another version of the driver that contains an updated copy of the Notify Object DLL or that contains an earlier copy of the Notify Object DLL, the new file is not copied over the previous file.


This problem occurs if the NDIS intermediate driver requires a Notify Object DLL for installation. The Notify Object DLL is not removed from memory when you remove the network component that it belongs to. Because of this, you cannot remove the .dll file from the %WINDIR%\System32 folder.

In this scenario, the device driver has unregistered itself from the registry, and has indicated that it can be unloaded. However, the Notify Object DLL is still locked in memory.
