Register Your Laptop


The following sections provide instructions for registering your laptop, configuring your system and accessing the Internet at Bobst Library. The instructions differ somewhat depending on what other types of connections to NYU-NET you have installed.

If your laptop has an NYU office connection, follow these steps:
  1. Registration
  2. Configure Networking Software
  3. Configure Client Applications
  4. Connect
If your laptop has a ResNet connection, you only need to follow these steps:
  1. Configure Client Applications
  2. Connect
If your laptop has no other connections, follow these steps:
  1. Install and configure the Ethernet card
  2. Registration
  3. Configure Networking Software
  4. Configure Client Applications
  5. Connect


To connect your laptop to NYU-NET at Bobst, you need:

  1. An IBM PC-compatible running Windows 2000 or later, with Client for Microsoft Networks and TCP/IP network components installed. These components are included with Windows XP and this document includes instructions for configuring them.
  2. A 10BaseT Ethernet adapter. Network cables are provided at the Bobst Library network ports. There is no need to obtain your own cable.
  3. An NYU email account, to which registration notification and periodic updates will be sent. NYUHome accounts, supplying email and other services, are available to students in degree or diploma programs and to NYU faculty and staff members. To activate your NYUHome account, you'll need your NYU ID number and your NetID. (Your NetID is usually printed in the lower left corner of your NYUCard.) Next, from any Internet-connected computer, go to, enter your NetID and current password, and follow the instructions.
  4. TCP/IP client software, including an up-to-date web browser (Firefox or Internet Explorer) and — optional for NYUHome users — Thunderbird. Antivirus and anti-spyware software are also highly recommended. This is the same set of Internet software used with ResNet and office Ethernet connections to NYU-NET. If you do not yet have them, but already have an Internet connection, you can download them directly from the NYU-NET Software page of this site (NetID and password may be required).


PLEASE NOTE: If you are registered for ResNet, or have already registered your laptop using the new NYU-NET Registration System, you are automatically registered for wired laptop access. Simply follow the configuration instructions below.

Ethernet Address

Your Ethernet address is a unique address associated with your Ethernet card. It consists of six pairs of alphanumeric characters (xx-xx-xx-xx-xx-xx). To find your Ethernet card address:

  1. Select Run from the Start menu.
  2. In the "Open" dialog, type cmd.
  3. At the MS-DOS Prompt, type ipconfig /all.

    Make sure that the name of your Ethernet card appears to the right of the words Description (see the illustration). If the Ethernet card is not in the computer, or if it is not properly installed, the PPP Adapter address may appear instead. This is not the address needed to register your laptop.

    If the Ethernet card is not listed, or if you can not run ipconfig.exe, see the Appendix on configuring your Ethernet card.

Once your application is processed, you will receive notification via email that your registration is complete. Registration generally takes two business days. If you have any problems completing the process, please contact the IT Service Desk.

Configure Networking Software

Note: If you have a ResNet connection, your networking software has already been properly configured. Go on to the next step, Configure Client Applications.

If this is the first time you are using your Ethernet card, you may need to install the Windows XP network components. See the Appendix on configuring your Ethernet card. To connect to NYU-NET from the library, you need to configure your networking software to use the DHCP protocol. DHCP is a one-to-many association of your Ethernet card's address to multiple IP addresses. This protocol allows you to move among multiple connection types with a single computer. Each time you start a session in the library you may be assigned a new IP number, even if you are plugging into the same port. This differs from an office or ResNet connection, where the same IP address is used every time you connect.

To configure your networking software, complete these steps:

  1. Configure your Ethernet card to use the TCP/IP protocol
    • Open the Network control panel. (Windows XP: Click on Start in the taskbar. Select Control Panel, and then Network Connections. (Windows 2000: Click on Start in the taskbar. Select Settings, and then Control Panel .)
    • In the Network Connections control panel (Windows 2000: Network & Dialup Connections control panel), under the LAN or High-Speed Internet section (Windows 2000: Local Area Connection section), click the right mouse button on the entry for your Ethernet card, and select Properties.
      Select Properties screenshot
      The Local Area Connection Properties dialog box for your Ethernet card opens.

      Ensure that Use this device (enable) is selected under the Device usage: section.
    • Click OK to close the Properties dialog box. You may need to re-open the Local Area Connection Properties window again, following the instructions above.
  2. Configure the TCP/IP protocol to use Dynamic IP Addressing
    • From within the Local Area Connection Properties control panel select TCP/IP or Your Ethernet card (TCP/IP), and click the Properties button.
    • Select Obtain an IP Address Automatically (make sure the button for that option is darkened).
    • Select Use the following DNS server addresses. For Preferred DNS server, enter For Alternate DNS server, enter

      There should be no addresses in the WINS addresses section (if there are, select them and click Remove). Also, Enable LMHOSTS lookup should be checked. Under NetBIOS setting, Default should also be selected.
    • Click the OK button to close the TCP/IP Properties sheet, then click OK to close the Network Connections control panel.
    • Windows XP may ask you if you want to restart the computer; click OK.

Configure Client Applications

Proxy Configuration

The Bobst Library plug-in ports access the Internet via a proxy server, providing a layer of security for your laptop and for NYU-NET. You can access any material on NYU-NET, including your NYUHome account and NYU Web, without making any adjustments for the proxy. When going beyond NYU-NET, each application handles the proxy a little differently. Visit the NYU-NET Proxy page on this website for more information and instructions.


Once configured, WinSCP can be used to download and upload files from the Internet and NYU-NET.


Telnet is not available with NYUHome service. If you have an NYU account on a machine which is accessible via Telnet, such as i5, we recommend that you connect using a Secure Shell (SSH) client such as PuTTY.


You can check your NYU E-mail using NYUHome as well as other email clients.

Retrieving Non-NYU Mail from Behind the Proxy Server

If you have a non-NYU account (for example, on a commercial ISP), you can check your mail by going directly to their website (for example,,, or, using Firefox or Internet Explorer. If you have an NYU account from which telnet is still available, you can also telnet to the account and use a host-based mail program, such as pine or elm, to check mail on the non-NYU account.

For more information on the proxy server—particularly its other uses—refer to the NYU-NET Proxy page on this website.

Connect to NYU-NET

To connect at Bobst Library, take your laptop to a designated laptop area on floors 2, 4 through 10 and the B-level. Plug one of the network cables provided into your network card, then start your computer. If your computer is already on, you will need to restart your computer after attaching the network cable. (Select Shut Down from the Start menu, then select Restart the computer and click Yes.)
