You can use the Lite version for Windows 2003 using a simple work around. Just stop Windows 2003 from forcing you to use CTRL+ALT+DEL on the machine. You can do this through local policy of the server.
To access group policy enter ‘GpEdit.Msc ‘ from command prompt. In the Group Policy Object Editor navigate to the following:
>Computer Configuration
>>Windows Settings
>>>Security Settings
>>>>Local Policies
>>>>>Security options
Double click on the policy for “Interactive Logon: Do not require CTRL+ALT+DEL” and enable.
You might need a server restart.
