I understand the function of an LDAP Ping over UDP/389 in the DC Locator process, but shouldn't that respond to a Portqry? When I test this I receive the following:
UDP port 389 (unknown service): LISTENING or FILTERED I've tested this in 3 separate forests against multiple domain controllers and I have gotten the same results in every case. All are 2008 R2 DFL/FFL. A Netstat -an does show this: UDP x.x.x.x:389 *:* Which seems to be correct for a UDP port that is also listening on TCP? I don't notice anything wrong in the domains, was just going through some firewall port requests and tested this. Is Portqry not a real test of this function? My next step will be to run a WireShark trace on a DC to look for this traffic.
