| Description | A driver packet received from the I/O subsystem was invalid. The data is the packet |
| Event Information | If a user types invalid characters other than (0-9 A-F) or types more than 12 characters for the media access control address by not using hyphens between bytes, Windows NT network driver interface specification (NDIS) cannot initialize the card and will result in event message(s). CAUSE: Some network adapter drivers allow an administrator to assign locally administered addresses (LAA) or universally administered addresses (UAA) for the installed adapter card. This allows administrators to manage media access control addresses and use it for inventory control and troubleshooting purposes. The media access control address consists of 6 bytes using HEX Numbers 0-9 and A-F, so a typical media access control address would look like this: 00-C0-4F-C9-F1-70 Most token ring adapter drivers present a dialog box during installation to allow the user to type the LAA media access control address. The field presented to the user allows for 17 characters and assumes the user is going to use hyphens between bytes. RESOLUTION: To resolve this problem, clear the invalid entry by performing the following steps: 1. Click the Start button, point to Settings, click Control Panel, and then double-click the Network icon. 2. Click the Adapters tab, select the installed adapter in question, and then click Properties. When the dialog box appears, verify that the media access control address displayed is valid or clear the entire entry and restart the computer. The media access control address being used can be displayed from an MS-DOS command prompt by typing: NET CONFIG WORKSTATION Workstation active on: NetBT_IBMTOK1 (00C04FC9F170) <--- media access control address |
