User can be locked out of system after sysprepping

[carlospuk]

Hi there

We ran into an issue where we sysprepped the server image, but needed to go back in and change something. (we forgot to delete C:\SkipIC.txt - it's a Windows Server 2012 box)

However, we're now locked out of the new Administrator account - and the password is hidden in the Sysprep answers file answer_server2008r2_amd64:

<AdministratorPassword>
<Value>ZQB1AGMAYQBzAHkAcwAwADYAMQA0ACEAQQBkAG0AaQBuAGkAcwB0AHIAYQB0AG8AcgBQAGEAcwBzAHcAbwByAGQA</Value>
<PlainText>false</PlainText>
</AdministratorPassword>

Is this default password documented somewhere? What is it? It would be very useful to have it documented in the Wiki or similar.

Hi Carl,

Eucalyptus will set the Administrator password of your windows instance,
which is retrieved by euca-get-password.
The password field in the sysprep xml has no use.

Hi Sangmin, yes it has no use if you're trying to get into the Eucalyptus instance, but if you're trying to get back into the original .img file running it under KVM, you are locked out! So does anybody have a copy of the decrypted password somewhere please?

One hack is to copy the config file:
https://github.com/eucalyptus/windows-integration/blob/master/EucaServiceLibrary/configuration.xml

and edit the password. then put it into floppy disk of the Windows VM, and
login using the new password.

Now that is a nice workaround - thank you!
