VMware flings

Ever wanted to have a fling with vmware?

A fling is little project engineers due for fun. Some turn into usable tools and utilities which might make your management easier.

Have a look and see if anything is interesting.

There is also a contest. The prize is a pass to vmworld.


Forgotten passwords are so fun. For me it seems to always be an issue when the user needs the virtual machine right away.

I had such an issue where a VM host received a new IP address and nobody thought about the guests on the machine.

The host in question was a Redhat 5 box running VMware server 2.0. There were two guests. One XP and the other Win7. The XP guest was easily changed but for some reason somebody changed the local administrator account on the Win7 guest and of course nobody admitted to it.

Luckily, there is a nice utility which can go into the registry hive and reset the Administrator password. This utility is called Offline NT Password & Registry Editor.

Get the latest version especially if you have Win7. The download will give you a ZIP file which contains an ISO file. You can build a CD or in this case use the ISO file.

After you have extracted the ISO, copy it to a directory on the host.  In my case, I put it with the vmware folder as the ISO file is small.

Once in place, power off the guest.  Edit the guest configuraiton.  For the Cdrom, select the ISO option and direct it to the ISO.

Power up the guest and it will boot the ISO and start the program.

It’s very simply to use.  The author has old documentation but it’s still useful for getting an idea how the program will work.  It’s located here.

Some things to make note:
1) the registry path will either be winnt or windows depending on the operating system and if there were upgrades rather then fresh installs.
2) I had to “blank out” the local administrator password as I did try to change it to the current and I could not logon after rebooting.
3) Sometimes the local administrator is disabled. Make sure you clear that before you reboot.

After I enabled the local administrator account; I was able to access the VM and change the network configuration and get the VM on the network.

Finally, if you think this should have pictures and a full blown walkthrough, please comment it and I will modify this post.
