Excel generation in a different thread fails.

I try to generate a excel workbook using Excel object in ASP.NET program.
When I implement the Excel workbook generation with out a thread it works
fine. When I wrap all the excel generation process inside a method, and
spin
this method in a different thread I get the following error:

"An unhandled exception of type 'System.UnauthorizedAccessException'
occurred in Unknown Module.
Additional information: Access is denied."

I am stuck with this. Waiting for comments & suggestions on how to
generate
a Excel work book in a different thread.

Thanks in advance.

when you start a thread, it runs under the default process security context,
not that of the creating thread. you will need to have the new thread
impersonate the security of the creating thread. also new thread will not be
associated the correct httpcontext, so if you need it, pass it.
