NBNS broadcast queries are fqdn
Posted on 2009-04-17
I have a Windows 2003 domain. Multiple sites.
We run WINS and DNS. The clients are in Hybrid mode, DHCP hands out WINS and DNS servers.
I checked the WINS stats and there was over 10,000 records not found. I started up wireshark and found that clients and broadcasting Name Queries for FQDN.
For instance since clients are in Hybrid mode it queries WINS, but WINS only has netbios names. So it is not found so then it broadcasts to find name.domain.com and it is not found. I have a lot of this traffic. What could be causing the clients to request fqdn over the netbios protocol? DNS is working fine and there are no problems resolving names across the network. All of the queries in question are for the DC's in the local site.
