1. Test your data jack and station cable
· Look into the data jack for mis-aligned pins. Do not attempt
to correct alignment. Inform RITS (firstname.lastname@example.org)
if you reside in a residence hall or UITS-Telecommunications (email@example.com)
if your data jack is located in an IUB office.
· Sometimes, the black, 4-wire station cable is installed incorrectly.
Make sure the end marked "wall" is in the data jack. In most
cases, this is not an issue with the new 8-wire, gray cables.
· Try swapping your station cable with another, "known good"
station cable. If available, try connecting a "known good"
computer to the data jack. If the data jack and station cable have no
network problems, proceed to next step.
2. Check your computer's network configuration
· Look at the back of the PC. Most working network cards will
have a green link light?
· Many IUB buildings use DHCP (dynamic host control protocol).
Contact the IUB - Network Operations Center (firstname.lastname@example.org) if you
wish to verify that you are using DHCP. Then, run "winipcfg".
Make sure the Ethernet card is selected (not "PPP adapter"
- which is the modem). In an IUB office or greek house, the IP ADDRESS
should start with 129.79.x.x or 156.56.x.x. In a residence hall, the
IP ADDRESS should start with 10.10 or 149.159 (example, 220.127.116.11
in Campus View. 10.10.1.23 is an example a computer that has not yet
gone through the RITS registration process). Click "Release",
"Renew" and observe if the PC gets an IP address again to
make sure dynamic addressing is working. If you receive an IP address,
the problem is most likely not with the network. If you do not receive
and IP address, proceed to next step.
· Open the Network Control Panel, and select the TCP/IP properties
for the Ethernet adapter. Go to the "IP Address" tab and make
sure, "Obtain an IP address automatically" is selected. Close
the TCP/IP properties. Select the properties for the Ethernet adapter.
Make sure that any speed, duplex, or media type settings are set to
"Auto Detect" or a similar setting. Close the Ethernet adapter
properties and "OK" to exit from the Network Control Panel.
Document any changes that you made and restart the computer. After restart,
recheck with "winipcfg". If no valid IP address is displayed
then there may be a problem with the computer and/or its Ethernet adapter.
Contact your LSP.
· Go to start, run, and run "command" to open a DOS
prompt. Type the command "ipconfig" to verify the machine
has an IP address. If the computer has a valid IP address, try pinging
the nameserver, 18.104.22.168. If no valid IP address is displayed and
the data jack has tested good, you may have a hardware or software problem
with your computer. Contact your LSP.
· Open the Chooser, click "Appleshare", and check for
Appletalk Zones. If none, open the Appletalk Control Panel and make
sure that "Ethernet" is selected in the "Connect via:"
box. If "Ethernet" is selected and <no zones available>
is displayed in the "Current zone:" box then there may be
a problem with the Mac and/or its Ethernet adapter. Contact your LSP.
From a command prompt, try to ping the IU nameserver, 22.214.171.124. If
alive, try multiple pings and look for lost packets. Report any loss
to your LSP.
