Hopefully this explanation will make sense, but what is the best way (if it is even possible) to pass along user credentials to preform a specific application from an ASP.NET MVC application. Currently I am working on trying to create directories on another server, we can't do this using the generic credentials that the application is running with; however, we have been told that we can if we pass the credentials of the user currently using the application along.

Currently we are running on IIS 6.0 but will be moving to IIS 7.0 in the near future and likewise we are using Integrated Windows authentication for the web applications.
