There are no physical modems connected to my PC, but I still need to allow the Dialler to dial numbers. To do this, I need to create a virtual modem and display it in device manager.
Could anyone elaborate on the process ?
regards,
Abhiroop

Break out the Windows Device Driver Development Kit, Visual C++, learn how to write drivers, and go for it!

Look at the Process class and just launch the command line "EXPLORER.EXE driveSpec:". For example "EXPLORER.EXE C:".

So, you want an Explorer window with access only to the removable drive?? Cna't do it. Explorer gives you access just like you opened My Computer. You'd have to write your own version of an Explorer window with just the functionality you want.

So you want to interupt the call to the print dialog in any application, think about what you are asking, try and imagine how that could be achieved. Break the job down into small steps:
Create an application that monitors all acitve applications on the current PC
Identify every print option in every application the user may be running.
Identify when a user clicks or hot keys a print option.
You may now begin to get an idea that this is beyond your skills. It is certainly beyond mine. I suspect the reason you have not got any responses is that most people read you request, shake their head and mutter idiot before moving on, I should have!

All right, I tried to make it simple for you, I pointed out that I have no idea how you are going to achieve this and even called you an idiot for attempting it. And still you come back, this time with code. This proves you are not a troll, it does not change the fact that this is a stupid requirement.
I won't help you as I have better things to do, theres an ant crawling up the wall, that will be more interesting than debating this idiotic subject with you.
Good luck pal, you're going to need it!

You're not going to be able to do this using all-.NET code. I don't know the specifics of how to do it, but you're going to have to basically replace the system's print dialog to do what you want. This is FAR from a trivial task. You'll need very advanced knowledge of Windows internals and COM programming, along with some C++.
Why? Because Windows Security does not have any facilities in it to do what you want. Assigning a seperate password to a resource is a very inefficient method of trying to protect that resource. Personally, I think you're wasting your time trying to do this. Windows Security is made in such a way that users have a single sign-on and don't have to worry about "yet another password" to remember to access any resource. The permissions to users and groups of users are assigned to the user based on their login token, this includes accessing shared devices such as printers.
Your current method does not stop a print job from running. Since the job is already being spooled when your code figures out it is there, the print job has already started happening. The only thing you can do is pause the printer, which pauses ALL print jobs going to it, even the ones by other users who have supposedly put in the proper password. This is easily defeated because the user can just resume the printer to get around your password.

You don't. Services should not expose a user interface.
