SYMPTOMS
After installing Service Pack 2, the Cabletron T20xx Token Ring network
adapter in your computer may no longer function properly.
Removing Service Pack 2 does not correct the issue.
RESOLUTION
To work around this problem, manually enter the hardware address for
the network adapter in the secondary address field in the driver
configuration screen.
To locate the hardware address for the network adapter, do the following:
- Reboot the computer to MS-DOS either from the Boot.ini menu or using
a bootable floppy disk.
- Run the setup utility for the adapter, it will display the correct
hardware address for the card. The number will start with 0000B8xxxxxx.
The serial number is located on the mounting bracket of the adapter, but
has no direct translation to the hardware address.
The setup utility software is available from Cabletron's FTP site at the
following URL:
NOTE: The network adapter may work with incorrect or "dummy" numbers, but
this may create other network problems.
STATUS
Microsoft is researching this problem and will post new information here
in the Microsoft Knowledge Base as it becomes available.
