An error on DNS Port 53 by Best Practices Analizer

[the blur]

I use SBS 2008, --> Best Practices Analzer:
It reports an error:

The DNS Server service should listen on DNS port 53, but that port is owned by the process.

-------------------

I can't find any infommation on this error message. This is reporting back to the SBS console as an exception, and I see the red flag every time I sign on. How do I correct this ?

thx

According to recent tests, released this week on a security list, allow Windows to resolve the DNS server address, it opens up a huge gap in most personal firewalls known as Tiny Personal Firewall 2.0 or AtGuard (and possibly others) . As the firewall allows any communication through the port 53 (UDP), to facilitate name resolution, a Trojan can use this to connect through that port and then send and receive commands, firewall without warning. The consequences of this are easy to grasp.
