Drive List Shows Only Program Drive in 16-Bit and 32-Bit Programs

• Microsoft Windows NT Server versions 4.0 SP4, 4.0 SP5
• Microsoft Windows NT Workstation versions 4.0 SP4, 4.0 SP5

SYMPTOMS

On a computer running Microsoft Windows NT 4.0 Service Pack 4 or Service Pack 5, when you attempt to open a file you may be able to see only the drive of the program you are running in the Open box in the following program types:

• 16-bit programs that uses the common dialog box



• 32-bit programs that uses the old-style user interface instead of the new Windows NT Explorer-style user interface

CAUSE

This behavior can occur if the network adapter and network protocols are not installed or disabled. Without a network loaded, WNetOpenEnum does not succeed at the beginning of the GetNetDrives function, the function exits, and the drive list is never initialized.
