Control asp.net app from other asp.net app

[Headless Rider]

Hello,

I'd write admin application whitch stops other asp.net
application by ADSI (on the same machine):

DirectoryEntry deApp = new DirectoryEntry
("IIS://localhost/W3SVC/1/Root/My_Other_App");
deApp.Invoke("AppDelete", true);

The result is of course Access Denied. What I must set up
or how to autenticate/authorize/impersonate to the admin
app to obtain right access for this action?

Thanks for help, HlR.
