start a new backgroud thread in Application startup of web application

Question

I want to start a backgroud thread during the application startup in a web application. I have created a thread like this

threadMonitor = new System.Threading.Thread(new System.Threading.ThreadStart(DoSomeWork)); threadMonitor.Start();

this is working fine in develeopment system in XP, when deployed in IIS server on Windows 2003 IIS 6.0. This thread start is not invoking the thread.
