For Option 1
Clients can be configure to use either the central DNS servers or your Active Directory DNS servers. Additional tools that IT Services use for diagnosing security and configuration issues will only apply for clients using the central servers.
If using the central servers, make sure that firewalls are configured correctly as per the previous section or lookups routed through the central resolvers may fail.
You cannot configure your clients to register their names and IP addresses automatically in DNS. This can cause application problems if the client Windows name does not match the first part of its registered DNS name. The simplest solution to this issue is to make sure that the names match.
Disabling dynamic DNS registration
Please ensure that you disable the default Windows option on clients to register the computer name and IP address in DNS at boot time. This causes extra load on the Oxford DNS servers and will result in errors being logged that may confused diagnosis of network or AD problems. Never disable this setting on domain controllers as this will also stop them registering their service records.
- Select Start , begin typing connection, select View network connections
- For each connection that might be used (usually named Ethernet and Wifi) visit Properties > Internet Protocol Version 4 (TCP/IP) > Properties > Advanced > DNS and deselect Register this connection's addresses in DNS
- Also disable this for IPv6 on each connection: Properties > Internet Protocol Version 6 (TCP/IP) > Properties > Advanced > DNS and deselect Register this connection's addresses in DNS
For Option 2
Clients must be configured to use your Active Directory DNS servers. It is a good idea to include at least one of the central resolvers so that clients can still locate internet services even if your domain controllers are unavailable.
You can configure your clients and servers to register their names and IP addresses dynamically in DNS. You must continue to use the normal mechanisms via the IT Services web pages to register them for addresses that can be resolved externally.
