Here you will find information how to bypass the Ctrl-ALT-DEL Logon Prompt for a Windows 2003 Server.
This security setting determines whether pressing CTRL+ALT+DEL is required before a user can log on. If this policy is enabled on a computer, a user is not required to press CTRL+ALT+DEL to log on. Not having to press CTRL+ALT+DEL leaves users susceptible to attacks that attempt to intercept the users' passwords. Requiring CTRL+ALT+DEL before users log on ensures that users are communicating by means of a trusted path when entering their passwords.
Note: If this policy is disabled, any user is required to press CTRL+ALT+DEL before logging on to Windows.
To disable (Enable) the policies follow the steps below:
1. From the Run line or from a command prompt enter GpEdit.Msc and press enter.
2. At the Group Policy Object Editor user interface navigate to the following:
3. Double click on the policy for “Interactive Logon: Do not require CTRL+ALT+DEL”
4. Set the property to “Enabled” and then select “OK” and close the Group Policy Object Editor dialog box
