Printing from service (Adobe Printer)

Hello,

I have rather a unique problem that only happens from a service when the
user is not logged in. This happens also on Window XP (SP1 & sp2) and windows
2000. Again this problem does not happen when the user is logged in. We have
a service that will start an instance of IE and generate an Adobe PDF from a
web page. We have designed an IE Browser Helper Object that will print the
current web page to the default printer (which is Adobe PDF). This works when
the service is started and run when the user is logged in - but does not when
the user is logged out. The service is started as a user administrator. When
the failure happens we can log into windows and see that the document is in
the Adobe printer queue with an error displayed.

Other symptom:
Printing of an office document utilizing the Adobe Printer DOES work.

I believe this is probably some sort of security feature within IE that is
preventing us from printing to the Adobe Printer. Any help would be greatly
appreciated.

Thanks,
Tom -
