Windows service with a message form

[TyB]

Hello,
I am trying to create a Windows service that consists of a simple form that will show a message.

The goal is to have this message be visible when no one is logged into a PC IE at the log in prompt screen.

I know that this is possible as we have tablet PCs that display a virtual keyboard at the log in screen.

I have no problem creating and deploying or running the service. The issue is that the form is never visible.

Any thoughts or tips would be appreciated.

I am running the service under the Local System account with the interact with desktop check box selected.

Thanks,

Ty
