Verify your IP address

Before you can register, you must have an IP address in the form 10.5.xxx.xxx. Once you are registered, you will have an IP address in the form of 131.212.xxx.xxx. If you are having problems accessing the registration web page, or if you have previously registered but can not access the network, follow the steps below to determine your current IP address, then refer to the IP address table for an explanation.

Win2000/XP: Run IPCONFIG

  1. Select START - Run.
  2. At the command line, type in: cmd and click OK.
  3. At the windows prompt, type in: ipconfig and press ENTER.

The IP Configuration window should be displayed as shown:

If you get the error message "Fatal IP Error", contact the ITSS Help Desk.

In the IP Configuration window, the Ethernet adapter should be listed in the white box (for ex: SMC EtherPower II 10/100). If a modem is listed, click on the down arrow and select the Ethernet adapter from the pull-down menu. If the Ethernet adapter is not in the list, contact the ITSS Help Desk.

Check the IP address listed, and compare it to the IP address table below.

IP address Explanation
10.5.xxx.xxx Your computer is properly configured. To initiate full network access, register your connection.
10.0.xxx.xxx Your computer is attempting network access via a nearby wireless access point. Temporarily disable your wireless access, then rerun IPCONFIG. For Windows 2000/XP:
  1. Click on START - Settings - Network and Dial Up Connections
  2. RIGHT-click on the Local Area Connection for wireless, select "Disable" from the pop-up menu.
  3. Run IPCONFIG.

or error message "Media disconnected"		 Check the Ethernet cable. Make sure you are using a valid Cat5 twisted-pair Ethernet (TPE) cable - phone or modem cables will not work for Ethernet connections. Check that the TPE cable is plugged tightly into the RJ45 jack on the Ethernet adapter and into the Etherjack in the wall. Click the Release All and then Renew All buttons.

If you still don't have an IP address in the format 10.5.xxx.xxx, contact the ITSS Help Desk.
169.xxx.xxx.xxx Indicates there is a problem contacting our network server.

Win2000/XP: Type ipconfig /release, press Enter, type ipconfig /renew and press Enter again.

  • If you get the error message, "A DHCP server could not be located" - check the Ethernet cable. Make sure you are using a valid Cat5 twisted-pair Ethernet (TPE) cable - phone or modem cables will not work for Ethernet connections. Check that the TPE cable is plugged tightly into the RJ45 jack on the Ethernet adapter and into the Etherjack in the wall.
  • If you get an error message "Operation was attempted on something that is not a socket," your operating system files are corrupted. You will need to restore or reinstall TCP/IP. See: Operation was attempted on something that was not a socket for details.

If you still don't have an IP address in the format 10.x.xxx.xxx, contact the ITSS Help Desk.

Win 98: Click on the Release All and then Renew All buttons. If the IP address does not change, unplug the RJ45 cable from the wall jack and restart your computer. Once it is up and running again, plug the cable in and run WINIPCFG or IPCONFIG again.

If you still don't have an IP address in the format 10.x.xxx.xxx, contact the ITSS Help Desk.
131.212.xxx.xxx You have a valid, registered IP address. If you are having problems accessing web sites or email, you may have a virus or corrupted network files. Contact the ITSS Help Desk for further assistance.
