Http error code 401 when I try a non login servlet
===

I access a non login servlet from my web browser, it responses as expected. I try to access the same servlet using the [WinINet Functions][1] and the parent process is windows service and the service is running under 'Local System Account'. I got the response in most of the machines, but results the error code 401 in few machines. But I could not reproduce in another machine. What would be the root cause of this?
