Hi,

some system in my network - not yet located - fires each some
minutes DNS requests, which then are forward to the default router
and thus the internet.

- Appears once 2 minutes latern, the 5 minutes later, in general
every 2-5 minutes later.
- Each time, 2 requests are fired. The requests go to the
primary and the secondary DNS server in parallel.

Does someone know a reason for that? Probably a M$ problem :-( ?

Ports 137-139 are blocked on the router.
