SYMPTOMS
When you are using a Microsoft Windows Millennium-based computer and you view the Driver File Details dialog box for a network adapter, you may notice that the Dc21x4.sys, rtl8139.sys, or E100bnt5.sys driver or drivers may list File is not installed in place of the driver file information for Provider, File version, and Copyright.
CAUSE
This behavior can occur when the driver is copied to the %windir%\System32\Drivers directory. Only drivers that reside in the %windir%\System directory display the driver file details in Device Manager. This occurs with a network interface card that uses the MPX EN5038 chip. These cards may come from a variety of manufacturers, including but not limited to: Compaq, Hewlett-Packard, Accton, RealTek, and SMZ.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
MORE INFORMATION
Steps to Reproduce the Behavior
- Right-click My Computer on the desktop, and click Properties.
- Click the Device Manager tab, double-click Network adapters, and then double-click the network adapter.
- On the Driver tab, click Driver File Details.
- Click dc21x4.sys or e100bnt5.sys or rtl8139.sys.
