Remote Desktop Question

Hello,

I am accessing a Windows XP PRO SP2 machine via remote desktop from a Vista
Home Basic machine. A week ago I tried to install a printer driver to the
Vista machine for the Dell AIO 960 printer that was directly connected to
the XP machine. Well that has been resolved but now each time I log onto
the XP machine via remote desktop, I get the completion screen to the
install program for the Dell AIO printer and asks me to print a test page,
etc.

Is there someplace in the registry that is causing this where I could go in
a prevent this from happening?

Thanks much in advance for any assistance.
