The information in this article applies to:

  • Microsoft Windows NT Server version 3.51

SYMPTOMS

Under certain circumstances, your Windows NT Server freezes completely when you use a 3Com 3C59x network card with Bus Mastering enabled.

CAUSE

The hang of the server is caused by a loop in the Windows NT 3.51 3Com 3C59x driver (from the Drvlib directory).

RESOLUTION

3Com provides a fix for the 3C59x network card driver (version 1.10.00).

The new driver, EL59x.sys (version 1.10), is available at the following WWW location as 3c59xx.exe (a self extracting file):
