Yeah, I forgot to mention that I had tried that. I shut down the
firewall service completely, but these errors continued to be logged.
Also, I have IPv6 disabled on the server.

 

Crazy.

John try shutting down the firewall and see if they go away.  If so then
you may have the same issue I had this morning with IIS v7.  It appears
that there is something in the internal firewall that does not like
certain features, and no I have not had time to trouble shoot this yet.
It might also be that you have the machine using IP v6 and IP v4.  I had
to shutdown IP v6 on my DNS/DS because I did not have a fixed IP v6
address for the machine.  Another trouble shooting thing for me to do.

I have a separate DNS server here for external queries. That server

I've shut down DNS on that server and moved its IP address to a new
Server 2008 server. But for some reason, the Server 2008 machine is
blocking all DNS queries from any other machine (on our network or off).
Windows Firewall is configured to allow inbound and outbound TCP/UDP
traffic on port 53, so that doesn't seem to be the issue. But I get a
ton of these in the Security Log:

=====
The Windows Filtering Platform has blocked a connection.

The 150.176.37.178 <http://150.176.37.178/>  machine is the DNS server,
and the 150.176.37.163 <http://150.176.37.163/> 
machine is I'm trying to do a query from using nslookup. But I've also
got lots of entries like these from other hosts trying to query the
server.

I'm stumped as to why this traffic is being blocked. Any ideas?
