Device Error Upgrading WFWG Over Windows with Intel Faxability

ID: Q93384

The information in this article applies to:

Microsoft Windows for Workgroups version 3.1

SYMPTOMS

After upgrading to Microsoft Windows for Workgroups (WFWG) version 3.1 from Microsoft Windows version 3.0 or 3.1 with Intel Faxability installed, the following error message occurs when you try to run Windows for Workgroups in enhanced mode:

A device has been specified more than once in the SYSTEM.INI file or a device specified in SYSTEM.INI conflicts with a device that is being loaded by an MS-DOS device driver or application. Remove the duplicate entry from the SYSTEM.INI file and restart Windows.

CAUSE

Both Intel Faxability for Windows and Windows for Workgroups install a virtual communications driver (VxD). When Windows for Workgroups upgrades, it places a second VxD in the [386Enh] section of the SYSTEM.INI file. Even though these drivers have different filenames, Windows for Workgroups sees them as duplicates because they are both virtual communications drivers.

Intel Faxability originally adds:


   DEVICE=CAS31VCD.386

Windows for Workgroups upgrade then adds:


   DEVICE=VCD.386

WORKAROUND

The following procedure eliminates the above error message:

Edit the SYSTEM.INI file with any text editor (such as Notepad).

Locate the [386Enh] section and find the following lines:
```
      DEVICE=CAS31VCD.386
      DEVICE=VCD.386 
```

To enable the default Windows for Workgroups driver, insert a semicolon (;) at the beginning of the DEVICE=CAS31VCD.386 line, as follows:
```
      ;DEVICE=CAS31VCD.386 
```
