PD with citrix presentation server 4.0

Hi, I have Server 2003 environment with thin clients connecting using Citrix with the thin clients. My new project requirement, require user to key in staff ID and password for printing. I have develope a authentication screen using C#.net 2.0, but the authentication screen has appear in server console instead of prompting to client. Any clue ?

I assume you are calling your program from the Run Program action? This will always display on the console because it is running from Print Distributor service under the context of the localsystem account.

What you might want to consider is writing each print file to a folder specific to a user, then have your program running on the client in the background monitor the folder. When Print Distributor writes the file your program can popup a dialog.
