NetworkInformationException in NetworkInterface.GetAllNetwork­Interfaces thrown when running as wind

[sebastian.dau]

Hi News Group,

I'm writing some code that discovers network interfaces and devices.
It works correct when executed in a console application (managed)
but it fails when executed from a managed windows service.
The service is configured to run as local service so I guess that is
enough permission to perform the operations.


Does anybody know how to discover network info from a windows service
and why my code does fail ???


See stack for info.


Even though it's managed code I know that the underlying function is
pure win api and the source of the error.

I wouldn't make the assumption that the service has sufficient
permission. I think you should try running the service with your login
info and see if the problem persists.
