Account Management Event ID 642 Anonymous Logon

There are more one one DCs (DC1 and DC2, DC1 is the PDC Emulator) in a domain.  An administrator changes an AD user account attribute, e.g. changing password/unlocking account, on DC2.

On DC2, two security events (628 (for password reset) and 642) are logged with the administrator user id.  On DC1 (the PDC emulator), only one event (642) is logged with NT Authority\Anonymous Logon.

I agree the event ID 642 on DC1 is created by the replication of the changes to the DC holding the PDC Emulator role.  Sometimes, I also see this happened on a non PDC Emulator DC.

Linux Guest Different MAC Address Error on VMware vSphere

Converted a Linux (Fedora 5) PC to a VMware vSphere guest.  The Linux guest OS shows a failed message when shutting down interface eth0.

Fix: edit /etc/sysconfig/network-scripts/ifcfg-eth0’s HWADDR to match the MAC address assigned the Linux guest OS.

Linux Guest Hangs at “Starting udev” on VMware vSphere

Converted a Linux (Fedora 5) PC to a VMware vSphere guest.  The Linux guest OS hangs at “Starting udev”.

Fix:

1. Restart the Linux guest OS;
2. Press any key at the GRUB boot menu, press e to edit, and add the highlighted words at the “kernel” line; press enter, and then b to boot;
   kernel /vmlinuz-2.6.18-1.2257.fc5smp ro root=/dev/sdb1 clock=pmtmr divider=10 hgb quiet
3. Once it boots in the console, edit /boot/grub/grub.conf with the same setting.
