Re: Problem with ssh on the vmguest machine
Hello All, I am able to make a reservation now on the windows image. The problem was with the cygwin configuration.I reinstalled it and it worked fine! Just in case this is helpful to anyone what I analyzed was: In case there are multiple accounts on your machine , then make sure the root account has admin access and install cygwin by logging into as root user. Thanks again to all for all the help. I have few more sysprep installation steps to follow.. I hope I face less obstacles hereafter.. :) On Fri, Apr 16, 2010 at 5:29 PM, Kiran N kiran.nellima...@gmail.com wrote: Thank you Andy !

Re: Problem with ssh on the vmguest machine
Ryan is correct. The root account is a normal Windows account in the Administrators group. The instructions/scripts do apply to all versions of Windows. You can create the root account via the GUI or run: net user root /ADD net user root password net localgroup Administrators root /ADD Once the account is created, logout and login as root.
