Hi Stian,

When you loose your DNS settings, does it happen all the time or just 
sometimes? I assume the latter is true. If so, can you identify what 
circumstance leads to the adapter DNS settings to disappear? Failed 
connection attempt before hand? An unexpected disconnect by the server?

Thanks,

-Matthew
