If you cannot log on, log off or restart remotely by using InterCLASS’s power control feature for particular student computers, please check to see if you can retrieve the correct IP address from the DNS server.

Here is how to check it quickly:

  1. Log on to the problem student computer and the teacher computer.
  2.  On the teacher computer, open the command prompt (Type in “cmd” in the search box of the Windows Start menu and then Enter).
  3.  On the command prompt, type in “ping (Computer Name of the student computer)”, and then you will receive a reply with the Hostname [IP address].

    For example, if the problem student computer’s name is STUDENT01, then type in “ping STUDENT01”, hit Enter, and then you should get a reply from STUDENT01 with the IP address from the DNS server.

    It should look something like this:

    ping STUDENT01
    Pinging STUDENT01 [(IP address from DNS)] with 32 bytes of data:
    Reply from (IP address): bytes=32 time=1ms TTL=128
    Reply from (IP address): bytes=32 time=1ms TTL=128
    Reply from (IP address): bytes=32 time=1ms TTL=128
    Reply from (IP address): bytes=32 time=1ms TTL=128

    Ping by Hostname

  4. Go to the problem student computer and then open the command prompt.
  5. On the command prompt, type in “ipconfig” and then Enter.  Your network information will appear, so please find the IPv4 Address of your network connection. This is the physical IP address of the computer.
  6. Please compare the IP address from the DNS server and the physical IP address of the computer. If they are different, then you will need to have your tech person delete the cached IP address from the DNS server.
  7.  Once the cached IP address has been deleted, the power control feature should work properly.
