SYMPTOMS
When you try to run a Microsoft Visual Basic 3.0 program in Windows, or try to start an MS-DOS session, you may receive the following error message:

A device attached to the system is not functioning

When you click OK, the program or the MS-DOS session may not start.



CAUSE
This error message can occur if either of the following files is damaged or missing:


 * Vbrun300.dll
 * Winoa386.mod



RESOLUTION
To resolve this issue, use the appropriate method:

Method 1
If you receive the error message when you try to run a Visual Basic 3.0 program in Windows, reinstall the Vbrun300.dll file. To do so, reinstall the Visual Basic 3.0 program that includes the Vbrun300.dll file on its Setup disks.

Method 2
If you receive the error message when you try to start an MS-DOS session, extract a new copy of the Winoa386.new file from your original Windows disks or CD-ROM to the Windows\System folder, and then rename the Winoa386.new file to Winoa386.mod. To do this, follow these steps:

 Extract the Winoa386.new file from your original Windows 95 disks or CD-ROM to the Windows\System folder. The Winoa386.new file is located in the following locations:

 The Win95_03.cab cabinet file on the Windows 95 and Windows 95 OEM Service Release 2 (OSR2) CD-ROM. The Win95_03.cab cabinet file on disk 3 of the original Windows 95 DMF floppy disks. The Win95_04.cab cabinet file on disk 4 of the original Windows 95 non-DMF floppy disks. The Win98_45.cab cabinet file on the Windows 98 CD-ROM.
