Define Multi homed server?

Server with 2 or more NIC cards.

DHCP Super scope

Combination of 2 scopes. Ex: 192.168.1.1 and 192.168.2.1

We combine these 2 to lease out the ipaddress no matter the network ID

One client can get 192.168.1.1 and another client can get 192.168.2.1

So now when client A wants to talk to client B. they can’t communicate as the network ID’s differ. Now we need to install RRAS on DHCP server.

In a scenario like this we need to have the default gateway as ipaddress of DHCP server.

Fault tolerance in DHCP

Coming to fault tolerance, we can’t have 2 dhcp servers with same scopes. We can only have 2 scopes with ipaddress divided.

If DHCP server 1 as 192.168.1.130 , we can have DHCP server 2 with scope as 192.168.131.254.

Domain controller for domain XYZ.com cannot be connected error message

When we are trying to add a client or server machine to a domain i.e. making a member of domain and when you receive an error message as “domain controller for domain google.com cannot be connected” make sure the preferred DNS ipaddress in the TCP\IP properties is correct, pointing to DNS server. As the DNS server has the srv records to connect to domain controller.

What is round robin in DNS?

Round robin: enables us to set multiple records of a given host name. and distributes the ip address in order. 

Ex:

Create a host name in dns as www. www.izone.com with ipaddress as 192.168.1.100

Create the same hostname with 192.168.1.200

Create the same with 192.168.1.300

When we try to ping the www.zone.com

Reply's as 192.168.1.100, 192.168.1.200, 192.168.1.300

Again ping www.izone.com

192.168.1.200, 192.168.1.300, 192.168.1.100

Again ping www.izone.com

192.168.1.300. 192.168.1.200, 192.168.1.300

So the order keeps on changing.
