Detailed configuration of primary/secondary DNS servers

Shanghai ms (Headquarters) has more than 800 nodes. subsidiaries, offices, and partners all over the world are remotely connected to the headquarters, what is the responsibility of the company as its in charge of the network! Details determine success or failure: network devices (such as routers, switches, firewalls), servers ...... Next to the PC, and even an OE (or outlook) configuration, backup, mail import, export, and so on all have very detailed paper documents and electronic documents! Points: the Division of Labor clearly defines the responsibility to each IT staff. If yes, it is integrated into a whole group!

PS: please do not attack our company's network. ^_^ do not block the number! Haha ...... If time permits me to "break down" the entire network into N blog posts, share them ...... Pai_^

The company uses a domain environment to build a DNS server. Other information is as follows: Svr1 primary DC1/DNS: IP address 192.168.1.22/24 (NIC 1) ip address 192.168.0.44/24 (NIC 2) Svr2 secondary DC2/DNS: IP address 192.168.1.23/24 (NIC 1) ip address 192.168.0.45/24 (NIC 2) Note: Nic 2 isNetwork Load Balancing ClusterUse it!

I. InstallationDNSService:

Win + R→Appwiz. CPLPress enter to open "add/DeleteProgram", Such:

The rest is OK → next → select the source disc ...... It's easy! Haha 2. Create a region:

(1) OpenDNSService Console, such: Win + R→Dnsmgmt. MSCPress enter to open"DNSAfter "service console", create a region, such:

 

Next, the page is displayed, such:

 

After the next step, for example:

 

Next → complete!

(2) create a reverse search area:

Follow these steps by referring to the forward search area. Note the following when you finish the steps:

 

The rest is very simple ...... Pai_^ ......

Iii. Major resource record: Note: It is often used by enterprises. Others are omitted!

(1) create a host record:

 

 

 Test whether the resolution is successful:

We can see that the resolution is successful!

(2) thinking: how to create a new one, as shown in? Similar to creating a host a record!

 

Iv. Interface Configuration:

 

V. Forwarding Server Configuration:

Vi. Advanced DNS settings:

(1) DNSRegional Transmission:Note: primary DNSSettings on! That is, svr1

 

 

Is the region replication settings for the reverse search area:

(2)InSvr2Set DNS region transfer on:Note: Secondary DNSSettings on! That is, svr2

First, test the connectivity and resolution:

 

We can see from the above that all are successful!

* InSvr2After installing the DNS service,Press enter in win + R → dnsmgmt. MSC. The following interface is displayed:

Next, the following page is displayed:

 

 

 

 

Next we will do the following:

 

 

 

 

Next → complete! Okay, let's see if synchronization is done. Please take a closer look! Pai_^

Svr1AndWhen svr2 is running normally, it operates on the client. The resolution is as follows:

 

Next we will simulate svr1If a fault occurs, disable the NIC.Nic, and then operate on the client, such:

Primary/secondary DNS server configuration is complete!
