doesn't work: "Start the following program at logon"

Hi all.

I have a Windows2003 terminal server, joined to my domain.

This machine works great for many RDP users.

I recently added a new domain user configuring the option "Start the

following program at logon".

The user logs on the machine, but he gains access to the standard desktop,

the program I configure doesn't start at logon.

I tried the same configuration of some other users who work fine, I tried to

start the "notepad.exe" or the "CMD.exe"... nothing.

The user always experience a standard logon. The setting on the "enviroment"

tab seems to be ignored.

The user is "clean".

No particular policies or other settings are applied.

I don't think the client computer configuration is involved.

I also tried from my laptop with the same results.

Can any of you help me to resolve this problem?

Really thank you for your help.
