Hi John,
Thank you for your update.
As I have mentioned before, if the MSDN sample works fine, there should be
some problems in this special application. Please try the following steps
on your side.
1. Restart IIS firstly.
2. Create a new web application and add your code to this new web
application step by step to check when the error occurs.
In addition, please tell me the detailed error message when the
server.transfer Error occurs.
On the other hand, I agree with you that it may be some kind of permission
problem. Please try to add the ASPNET account (or the other accounts if you
have impersonated a Specific User for All the Requests of an ASP.NET
Application) to the administrators group. Then test this issue again.
I hope it helps.
Best regards,
Jacob Yang
