When I run a network sniffer i get several of the following errors
Source: 184.108.40.206 (PC)
Destination: 220.127.116.11 (Switch)
Info: Domain/Workgroup announcement <my domain controller name>
info: name query, nb_illegal nescon(00)
Question: My domain controller is on a 192.203.x.x network
How does the 192.201.x.x network know of the domain controllers existence
The PC whose address is 18.104.22.168 has a second NIC which is on the 192.203.x.x network
Question 1: How do I stop my domain controller from broadcasting to other subnets that are physically separate (no VLAN's configured, but each network has its own switches with no routers to other switches)?
Question 2: If I have hardcoded ip addresses how can i stop my dns from broadcasting? Should I use WINS on top of DNS? There are 12 PC's connected to the domain controller. I want to stop browser elections and browsing? If browsing stops are there any negative effects?
I also have problems where computers added to the domain take longer to ping the domain controller then computers on the same subnet that aren't added to the domain.
I am using layer 2 switches
