If a computer is not able to access server drives, or is experiencing internet connectivity issues, it may be because it has fallen off the domain. You can check if a computer is on the domain by hovering your mouse cursor over the network icon on your taskbar as shown below:

Where the above example reads “Network 2” your lab computers should show the domain name. This should be in the format XXX-SmartLab.Local (where XXX are your schools initials, this may be 3 or 4 letters). If it does not show this domain name, then the computer is not on the domain.

Follow the steps below to add the computer back to the domain and resolve related issues. Remember that the student computers must be thawed in Deep Freeze before making changes, or the changes will reset when the computer is rebooted:

Step 1 - Log in to the server computer. This is a desktop “tower” computer located under the facilitator's desk. There is a second keyboard/mouse/display at the facilitator's desk to control the server.

Step 2 - Press Start and search “CMD" to find Command Prompt. Open this application.

Step 3 - In Command Prompt, type "ipconfig" without the quotation marks and press enter.

Step 4 - Locate the “IPv4 Address” and write down this number.

Step 5 - On the computer that has fallen off the domain, login and search for “Control Panel.” Open this application.

Step 6 - Click “Network and Internet” > “Network and Sharing Center” > “Change adapter settings”

Step 7 - You'll now see the page below. Right click the ethernet adapter and select “properties.”

Step 8 - Highlight "Internet Protocol Version 4" and click properties.

Step 9 - Verify “Obtain an IP address automatically” is selected. Verify “Use the following DNS server addresses” is selected. The “Preferred DNS server:” should match the IPv4 Address you found on the server computer. You can set the “Alternate DNS Server:” to 8.8.8.8

Step 10 - Click “OK” on this window and on the Ethernet Adapter Properties window. 

Step 11 - Press Windows key + I 

Step 12 - Go to System > About 

Step 13 - In the About section, click the Advanced system settings

Step 14 - In the System Properties window, go to the Computer Name tab 

Step 15 - Click “Change”

Step 16 - Make sure “Domain” is checked and type in the correct domain name. This should be in the format: XXX-SmartLab.Local, where XXX are the school initials. You can check the domain name on another computer which is connected by hovering your mouse over the internet icon on the taskbar.

Step 17 - Click OK and you will be required to enter a domain admin user account and password. Use the Einstein account.

Step 18 - You will need to restart after joining the domain for the changes to take effect.

Step 19 - After restarting, the computer should now show that it is on the domain when you hover your mouse over the internet icon on the taskbar.
