ASP.NET

Some Details

I am working with VisualWebGUI, so this app is like ASP.NET, and it is deployed on IIS 7 (for testing)
For my 'Web Site', Anonymous Authentication is set to a specific user (DomainName\DomainUser). In my web.config, I have impersonation on. This is how I got my app to access the share in the first place.

The Problem

There is a point in the the app where we use the Thread class, something similar to:

Thread myThread = new Thread(new ThreadStart(objInstance.PublicMethod));
myThread.Start();

What I have noticed is that I can write to my logs (text file on the share), everywhere throughout my code, except in the thread that I kicked off. I added some debugging output and what I see for users is:

The thread that's kicked off: NT AUTHORITY\NETWORK SERVICE
Everywhere else in my code: DomainName\DomainUser (described in my IIS setup)

OK, for some reason the thread gets a different user (NETWORK SERVICE). Fine. But, my share (and the actual log file) was given 'Full Control' to the NETWORK SERVICE user (this share resides on a different server than the one that my app is running).

If NETWORK SERVICE has rights to this folder, why do I get access denied? Or is there a way to have the thread I kick off have the same user as the process?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
