Err Msg: Cannot Find a Device File That May Be Needed to Run...

Symptoms
When you restart your computer after installing the Dial-Up Adapter, you may receive the following error messages:
Cannot find a device file that may be needed to run Windows or a Windows application.

The Windows registry or SYSTEM.INI file refers to this device, but the device file no longer exists ...

If you still want to use the application associated with this device file, try reinstalling that application to replace the missing file.
The following files are listed as missing:
Vnetsup.vxd
Nwlink.vxd
Nwredir.vxd
Nscl.vxd
Vredir.vxd
Ndis.vxd
Ndis2sup.vxd
Vnetbios.vxd
Ndiswan.vxd
Two additional dialog boxes may appear informing you that the followingtwo files cannot be found:
Nwnp32.dll

After you acknowledge these error messages, Windows starts normally butwithout Dial-Up Networking functionality.
Cause
This problem can occur if you install Dial-Up Networking, Dial-Up Adapter, or Virtual Private Networking and then cancel Setup while the Copying Files dialog box is displayed. The Dial-Up Networking files are not copied to the hard disk but the file names are added to the registry. When the computer is restarted, the files are requested and cannot be found.

  2. In Control Panel, double-click Add/Remove Programs.
  3. Click the Windows Setup tab, and then click Communications.
  4. Click Details, and then click to clear the Dial-Up Networking check box.

  7. Click Start, point to Settings, and then click Control Panel.
  8. In Control Panel, double-click Add/Remove Programs.
  9. Click the Windows Setup tab, and then click Communications.
  10. Click Details, and then click to select the Dial-Up Networking check box.
