Starting Windows Application from .NET Web Service

I am developing a .NET web service using Windows Server 2003 and IIS 6.0
which consumes customer information and then attempts to create a new
customer account in an accounting application (i.e. QuickBooks). For
unattended access to the accounting application, an exception for the
application attempting to access the accounting application must be granted
through the accounting application user interface the first time.

I am able to activate this exception dialog box through a Windows
application, however, calls to my web service results in an error,
essentially telling me that I don't have the necessary exception, but not
activating the exception dialog box in order to grant the exception. Once I
have the exception, the web service can access the application without user
intervention.

Something is preventing the web service from activating the necessary
accounting application exception dialog box. I have attempted numerous
configurations including the following: running the application pool under
an administrative account (for testing purposes), setting the "Allow service
to interact with the desktop" property for the World Wide Web Publishing and
IIS Admin Service, verfiying the ACLs of the appropriate folders, and
changing app pool uesr accounts. In addition, there is a configuration where
I can use an out-of-process COM server supplied by accounting application to
perform the same operation. This configuration yields the same error.

What other configuration issues might prevent the web service from
successfully activating the exception dialog box? Is there an issue that
would prevent the web service from interacting with the desktop?
Alternatively, Is there a way to configure a specific security context for
the accounting application? I would appreciate any insights.

Thank you.
