I am trying to install ASPExec on IIS 4.0 to run a DOS application.  I have

tried to configure it according to the directions but I have run into a

problem.



The installation requires that "Allow service to interact with the desktop"

be enabled.  IIS is running as a service and this option is only available

if the "Logon as" option is checked.  My problem is that the login section

is grayed out and I don't know how to get to it.



I appreciate any help anyone has to offer.
