Deployment Solution

I'm trying to make a Windows 7 image with DS 7.5 where, upon bootup, the local administrator account is *not* disabled.

One catch: for reasons of simplicity and speeding up support, I have a GPO that renames the local administrator account to "ali". After capturing an image, then deploying the image to a PC, I try logging with ali and the password, and I get incorrect login or password. I try logging in with "administrator" and the password, and I'm told the account is disabled--sysprep obviously renamed the account back to "administrator".

The article found at http://www.symantec.com/business/support/index?page=content&id=TECH185748&actp=search&viewlocale=en_US&searchid=1418313251565 lists, as a solution, to use their supplied unattend.xml, which has the following code. This didn't work; should I change "administrator" to "ali" here?

<component name="Microsoft-Windows-Deployment" processorArchitecture="@ProcessArchitecture" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <RunSynchronous>
                <RunSynchronousCommand wcm:action="add">
                    <Order>1</Order>
                    <Path>cmd /c net user administrator /active:yes</Path>
                    <Description>Enable Admin</Description>
                </RunSynchronousCommand>
            </RunSynchronous>
        </component>

Thanks!

To clarifywhat Andy has said here, typically this is done directly in the XML using Microsoft elements. 

We do this in the oobesystem pass, using the UserAccounts element as follows,

   <settings pass="oobeSystem">
        <component name="Microsoft-Windows-Shell-Setup" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <UserAccounts>
                <LocalAccounts>
                    <LocalAccount wcm:action="add">
                        
                        <Name>myLocalAdmin</Name>
                        <Password>
                            <Value>mypassword</Value>
                            <PlainText>true</PlainText>
                        </Password>
                        <Group>Administrators</Group>
                    </LocalAccount>
                </LocalAccounts>
            </UserAccounts>
        </component>
    </settings>
