Domain Name
The Domain name that will be used in this small business is hongling.com .
DHCP configuration
- Assign a static IP address, subnet mask and default gateway for the DHCP server (Server I)
- install DHCP on DHCP server
- configue DHCP server:
- Create the scopes for the two subnet
- Select configure DHCP options later
- Activate the two scopes
- Configure the gateway for the two scopes (in each “scope option”)
- reserve IP address for WINS servers, DNS servers
- Install and configure DHCP relay agent on Server III on the first floor:
- Install DHCP Relay Agent on the server
Configure the IP address of the DHCP server to:192.168.2.101
- Configure:
- Enable DHCP clients
On each DHCP clients, choose “obtain IP address automatically” in TCP/IP properties dialog box.
WINS configuration
- Install WINS on both Servers
- Configure WINS in DHCP
in each scope option
- Find WINS clients by using “find by owner”
- configure WINS replication
Then, initiate replication immediately.
DNS configuration
- Install DNS on both DNS Servers
-
Create standard primary zone on the Primary DNS Server (Server II)
- Create root zone
- Create new forward Lookup zone
Create two new Reverses Lookup zones
Add all clients and itself to the forward and reverse lookup zones.
-
configure standard secondary zones on the Secondary DNS Server (Server I)
Create forward Lookup zones
- Configure zone transfers
- On the Secondary DNS Server, modify the SOA Resource Record:
Set “Primary Server” to “pdns.hongling.com”
Leave other properties to default value
- Configure the Primary DNS Server to notify the Seconary DNS Server whenever changes to zone occur.
Set “Secondary Server” to “sdns.hongling.com”
Leave other properties to default value
- Configure in DHCP server
In server option:
006 DNS SERVER:
Primary DNS Server IP address.
192.168.2.102
Secondary DNS Server IP address.
192.168.2.101
- On all DNS Clients, set “Obtain DNS server address automatically” in TCP/IP properties.
- Configure to allow dynamic updates
- Configure the DNS Server
Select “Yes” in the Allow dynamic updates list box
- Configure the DHCP Server
Select “automatically update DHCP clients information in DNS” check box, leave other properties to their default value.
- Configure all DNS clients
Select “Registrate this connection’s address in DNS” on the DNS tab of TCP/IP properties dialog box.
Replication and backup details
DHCP database will be automatically backed up to the directory of systemroot\system32\dhcp\backup\jet\new. DHCP will performs a consistency check of its database and attempts to fix any errors every time when DHCP service starts or thereafter periodically.
WINS database replication has been configured on both WINS servers in this network. It provides fault tolerance for NetBIOS name resolution. Therefore, if one of them fails, the other one continues to provide the WINS service on the whole networks. The two WINS servers are configures as the pull/push partner to each other. The replication will take place everyday in midnight and midday when the network traffic is not very heavy, or when 10 changes to the WINS database appears. This configuration will get a balance between network traffic and databases synchronization. (For details of WINS replication, please refer to WINS configuration.)
To provide DNS fault tolerance, two DNS servers are provided to host the zone of hongling.com in the network. The primary one contains the standard primary zone database file and the secondary one contains the secondary zone database file. Zone transfers are configured to replicate the zone database file from the primary DNS server to the other one. The secondary server will request for new data when refresh interval reached, and the primary server will notify the secondary server to update when changes happen. (For details, please refer to DNS configuration.)
