SYMPTOMS
You may experience intermittent network problems such as logon validation errors and network connection failures when running Windows for Workgroups with a 3Com Etherlink 16 (3C507) network adapter.



CAUSE
These problems occur due to a problem with the 3C507 enhanced mode NDIS driver.



WORKAROUND
To work around the problem, do the following:


 * 1) Run 3C507.EXE from the floppy disk (EtherDisk) that comes with the network adapter and set the Data Mode to Standard. The default factory setting is Turbo.
 * 2) Choose the Network Setup icon in the Network group. In the Network Driver dialog box, select the 3Com EtherLink 16 [NDIS2/NDIS3] driver.
 * 3) Select Real Mode NDIS Driver for the driver type. Choose OK and reboot the workstation.



STATUS
Microsoft has confirmed this to be a problem in Windows For Workgroups version 3.11. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
