Switching to Internet Access

Goals

Connect to the Internet to Perform Updates

During the initial set up of the server or while performing maintenance operations on the duplicate server outside of the prison you may need to connect to the Internet. This is particularly relevant for Windows Update and vSpace Update. Please limit the Internet activity to the bare minimum, namely those update operations. There will be no Internet access in the production lab so we don't want to risk accidentally changing something that might introduce a dependency on connectivity or install software that is not included in the EJP Recovery Drive

Do not connect the Server to a public network while DHCP server is active

The server in the production lab is responsible for providing DHCP services to the clients. This protocol uses generally uses broadcast messages to accomplish this. If you conncted the server to another network while it was still serving DHCP, then bad things will happen as this server will attempt to service the DHCP requests of the clients on that network.

Change the IP settings of the Teamed NIC

Assuming you have already completed the NIC Teaming configuration, you'll need to set the IPv4 settings of the Teamed Network Interface to match the network you are on. I don't have specific details about the wired network ports at the EJP office, but my assumption is that setting the interface to DHCP addressing will be sufficient. Note that you will only need to attach 1 of the interfaces.

Revert back to the static configuration

Once you are confident you are ready to go back to the static config, you'll want to set the Interface back to the static ip of 192.168.1.1 and subnet mask of 255.255.255.0.

Procedures

Open Services

• Open Start Menu
• Search for Services
• Select Services

Select DHCP

• Browse the services list looking for DHCP Server

Stop DHCP Server

• Observe that the DHCP server is Started (running)
• Click on Stop
  • You could right click on the service and select stop as well

Wait for DHCP to stop

• When the DHCP server is stopped the status will be blank instead of Started

Open Network and Sharing Center

• Click on Network Icon
• Select Open Network and Sharing Center

Change adapter settings

• Click on Change Adapter Settings

Select the Team COnnection

• Select the Team connection
• The name will probably be Local Area Connection 3
• The description would be HP Network Team
• Right-click on it and select Properties

Set DHCP for IPv4

• Select Obtain IP address automatically
• Select Obtain DNS server adddress automatically
• OK

Plug 1 network cable into your local network

• Only connect one interface
• It doesn't matter which one

Perform the Internet-dependent operations

• Do your Windows Update or vSpace Update or what not

Unplug the internet connection

• Make sure you are not connected to the local netowrk

Restore Static IP

• When you are done set it back to:
  • IP Address: 192.168.1.1
  • Subnet Mask: 255.255.255.0
  • DNS server 127.0.0.1

Restart DHC server or just reboot

• Now you can restart the DHCP server service
• If you prefer jsut restart the server
