Abstract LCCM LAN CONTROL MANAGER UNABLE TO CONNECT WITH CLIENT Symptom The LCCM LAN communication control manager is unable to connect with the client using the RPL protocol. Remote boot fails. Problem ISO This tip applies to IBM PC Model PC300GL, M/T6272 and M/T6282, with integrated 10BaseT Ethernet support. Affected systems can be identified by viewing the onboard ethernet adapter's MAC address in the F1 Setup utility. To view the MAC address, use the following steps: 1. During POST press the F1 key to run Setup. 2. Highlight "Devices and I/O Ports" and press . 3. Highlight "Ethernet Setup" and press . 4. Observe the line titled "MAC Address." If the MAC address begins with "00 06 29" this tip applies. Fix Download and run the utility MACUPDAT.EXE. Running MACUPDAT.EXE will create a bootable diskette. Cold boot the affected system from this diskette and note the on-screen message. The utility will notify the user that the MAC address has successfully been updated. The user will also be notified if the MAC address is valid and no updates were made. After the utility has run, remove the diskette and reboot the system. Applying the MACUPDAT.EXE utility to an unaffected system will not harm or alter the system. Applying the utility to an incorr- ect, or unaffected system will produce the following, or similar message: This machine MAC address: FFFFFFFFFFFF NO UPDATE NEEDED ! MACUPDAT.EXE may be downloaded via the Internet from the IBM Personal Computer File Library by searching the following Internet URL: www.us.pc.ibm.com/files.html MACUPDAT.EXE may also be obtained from the IBM PC Company BBS by calling 919-517-0001.
