Using Windows in my IUB or IUPUI campus housing residence, what should I do if I'm having trouble connecting to the campus network?

Note: You can use Get Connected to register your Windows 7, Windows Vista, Windows XP, or Mac OS X (10.3 and later) computer to use the Indiana University network in campus housing. Computers running Windows 2000 or Linux, as well as game consoles, must be manually registered. For help, contact the UITS Support Center. You cannot register earlier versions of Windows on the IU network in campus housing.

Network card configuration

If you're having problems connecting to the Indiana University Bloomington or IUPUI network with your Windows computer from your campus housing residence, you should first make sure that your computer's network card is configured correctly.

Check your 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: If you live in non-Greek campus housing, you will find an Ethernet 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:

In Windows Vista, from the Start menu, open 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.

If you receive an error message, see the appropriate section below:

Error messages

No domain server

This error occurs when a Windows NT Domain server (ADS) attempts to validate your password in Microsoft Networking, but can't because the server either was not available or could not be found. If you receive this error, follow the steps for your operating system:

In Windows Vista:

1. From the Start menu, open Control Panel. In the left menu, click Classic View. Open Network and Sharing Center, and then from the menu on the left, click Manage Network Connections.
   
   
2. Right-click Local Area Connection and select Properties.
   
   
3. Verify that Internet Protocol Version 6 (TCP/IPv6) is unchecked. Select Internet Protocol Version 4 (TCP/IPv4), and then click Properties.
   
   
4. Select Obtain an IP address automatically, and then click OK.

In Windows XP:

1. From the desktop, right-click My Network Places, and then select Properties.
   
   
2. Right-click Local Area Connection, and then select Properties.
   
   
3. Select Internet Protocol (TCP/IP), and then click Properties.
   
   
4. Select the radio button next to Obtain an IP address automatically, and then click OK.

If this error persists, it could be that the network is very busy. Click Cancel and try logging in again.

Duplicate computer name

For instructions on how to resolve a duplicate computer name error in Windows, 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 the UITS Support Center in Bloomington at 812-855-6789 or in Indianapolis at 317-274-4357.

DHCP error

This error occurs when your 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. Follow these steps:

1. From the Start menu, select Run... .
   
   
2. In the "Open:" field, type cmd and click OK.
   
   
3. At the command prompt, enter ipconfig/all . Press Enter. A list of networking information will appear.
   
   
4. When you see the IP address information, if you see a "169.x.x.x" number for your IP address, restart your computer through the Start menu.

If the numbers still do not appear, contact the UITS Support Center in Bloomington at 812-855-6789 or in Indianapolis at 317-274-4357.

The IU Secure wireless network is available in all IU Bloomington and IUPUI residence halls (with the exception of Wright), along with the Campus View Apartments. If IU Secure is not yet available in your campus residence, you may operate a properly configured 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 residence hall does not yet have IU wireless network access, how do I configure a wireless access point?
