Troubleshooting campus network connections in IUB or IUPUI campus housing using Windows
Note: Use Get Connected to register Windows 7, Vista, XP, and Mac OS X 10.5 and later computers to use the Indiana University network in campus housing. Computers running earlier versions of Mac OS, Linux computers, and game consoles must be manually registered. For help, contact your campus Support Center. You cannot register earlier versions of Windows on the IU network in campus housing.
If you're having problems connecting to the Indiana University Bloomington or IUPUI network with your Windows computer from your campus housing residence, check the following:
Physical connection
Network cable
-
IUPUI: In Ball Residence Hall and the Campus
Apartments on the Riverwalk, you may use a commercial
Ethernet cable.
-
Indiana University Bloomington: In Briscoe, Union
Street Center, and the Tulip Tree apartments, you will need to provide
your own standard cat6 Ethernet straight-through patch cord. In all
other non-Greek campus housing, you will find an Ethernet crossover
cable attached to the wall data jack.
IUB Greek housing residents may purchase an IU proprietary Ethernet cable; see At IUB, where can I purchase an Ethernet cable?
Data jack
If the room contains more than one data jack, try the other. All data jacks are active, but this can isolate the one with a problem.
Disable dial-up networking
If your computer keeps trying to dial the phone, disable dial-up networking:
Note: This is not an issue in Windows 7.
In Windows Vista, from the Start menu, click
Control Panel. In the left menu, click Classic View,
and then open Internet Options. Click the
Connections tab, and then select Never dial a
connection.
In Windows XP, from the desktop, open My Computer,
and then Dial-Up Networking. From the Connections
menu, choose Settings. Under "When establishing a network
connection:", select Don't prompt to use Dial-Up Networking.

Duplicate computer name
See In Windows, why do I get an error about a duplicate computer name?
Unable to browse the network
When you receive this error, your computer is unable to connect to the network, and therefore cannot send or receive data. Double-check the configuration settings and your network cable. If you have done this and the problem persists, contact your campus Support Center.
DHCP error
This error occurs when your Windows XP computer cannot communicate with the DHCP server, which is necessary for leasing an IP address to your computer. If you encounter this error, it might be that your computer cannot pick up the IP address automatically. To fix this:

Startmenu.
After restarting, if you still see this error, contact your campus Support Center.
The IU Secure wireless network is available in all IU Bloomington and IUPUI dormitory residence halls, as well as Campus View and Hillcrest Apartments. If IU Secure is not yet available in your campus residence, you may operate a properly configured, FCC-approved wireless access point (WAP) as an exception to the IT-19 Extending the University Data Network and IT-20 Wireless Networking policies from the University Information Policy Office (UIPO). Once IU Secure is available in your residence, this exception will no longer apply and you will need to remove your WAP from the network. For details, see At IUB, if my campus residence does not yet have IU Secure wireless network access, how do I configure a wireless access point?
