AD Authentication Failure after Reverting to Previous Snapshot

A successful configuration of Samba and Winbind allowing users to login to a Linux virtual computer using ones Active Directory credentials might stop working after a few weeks. If the virtual computer was reverted to previous snapshot between machine password changes in AD, the AD controllers will not let the computer authenticate again due to machine password mismatch.

How to install VMware Tools on Linux

VMware Tools is a set of drivers and utilities to make a virtual computer perform better and faster inside a virtual hosted environment. It makes a virtual computer aware of its host at least to some degree.

Once I managed to install the VMware Tools on a Linux based virtual computer properly, I have decided to write it down for good.

VMware Tools is a set of drivers and utilities to make a virtual computer perform better and faster inside a virtual hosted environment. It makes a virtual computer aware of its host at least to some degree.

However, the VMware Tools must always be in sync with the running kernel on a Linux based virtual computer and keeping them up to date can be tricky business. Once I managed to do it properly, I have decided to write it down for good.

How to virtualize PC

Have you ever come to the point when you had to perform a clean Windows installation on the working computer? However, you have all the software, you use on the daily basis, installed and configured. Reinstalling the Windows and all the software again usually takes you at least a week. Can’t afford to stay offline this long?

This way you have time to do the installation and setup of the new environment, while you can always log in to the virtualized old computer and do all the regular tasks that come in meanwhile.

This procedure is also referred as physical to virtual conversion or P2V for short.

On the other hand, you can favour fixed size VHD files, and later discover you overdimensioned the virtual disk drive. How to make the fixed size VHD file smaller without converting it to the dynamically expanding type?

VHDMount utility and Symantec Ghost saves the day one more time. Here’s the procedure:

I am going to describe a quick way to convert Symantec’s Ghost GHO file to Microsoft Virtual Hard Drive VHD file. The process will not require a setup of a virtual machine. You’ll need:

  • The VHDMount utility, which is distributed as a part of Microsoft Virtual Server but can be installed seperately.
  • The GHOST32 utility, which is a part of Symantec Ghost installation.
