What is my IU Network ID?

Your Network ID is your electronic identity at Indiana University and consists of two things: a username and a password (often referred to as your network password).

What can I do with a Network ID?

You can use your Network ID to create additional accounts using the IU Bloomington Network ID Services and IUPUI Network ID Services utilities available on the World Wide Web. Choose the appropriate URL below for the campus where your accounts are located:

Your Network ID is also your key to host-independent services, such as IUB and IUPUI dialin modems. Your Network ID is part of the authentication process when you log into the Shakespeare systems and the Jewel systems. You also need it to log into the Macintosh computers in the Student Technology Centers at IUB and at some centers at IUPUI. You may also use your Network ID to obtain software via IUware.

Do I have a Network ID?

If you obtained your first IU computing accounts after January 10, 1994, your Network ID accompanied those. Your network password was initially synchronized to your first login password.

I don't have a Network ID. How do I get one?

The answer to this question depends upon whether you are a student, faculty, or staff member. See the Knowledge Base documents How do I get an Indiana University Network ID? or At IUPUI, how do I get my first computing accounts?

Can I change my network password?

If you have a Network ID and would like to change you password, use the Password Maintenance utility at:

  https://password.iu.edu/

This will also reset your passwords on most other UITS shared central systems.

I've forgotten my network password. What can I do?

If you have forgotten your Network ID password, see the Knowledge Base document If I forget or have problems with my Indiana University network password, what can I do?

What is NTFS?

NTFS, short for NT File System, is the most secure and robust file system for Windows NT, 2000, and XP. It provides security by supporting access control and ownership privileges, meaning you can set permission for groups or individual users to access certain files.

There are currently two versions of NTFS being used in Microsoft operating systems. NTFS 4.0 is the file system used with Windows NT 4.0. NTFS 5.0 was released with Windows 2000, and is also being used in Windows XP. NTS 5.0 provides some additional capabilities which were not included in NTFS 4.0. Both versions of NTFS share the following features:

• NTFS supports compression of individual files and folders which can be read and written to while they are compressed.
• NTFS is a recoverable file system, meaning it has the ability to undo or redo operations that failed due to such problems as system failure or power loss.
• NTFS supports Macintosh files.

In addition to the above features, NTFS 5.0 (used with Windows 2000 and XP) also provides the following functionality:

• Disk quotas: Administrators can limit the amount of disk space users can consume on a per-volume basis. The three quota levels are: Off, Tracking, and Enforced.
• Encryption: The NTFS 5.0 file system can automatically encrypt and decrypt file data as it is read and written to the disk.
• Reparse points: Programs can trap open operations against objects in the file system and run their own code before returning file data. This feature can be used to extend file system features such as mount points, which you can use to redirect data read and written from a folder to another volume or physical disk.
• Sparse files: This feature allows programs to create very large files, but to consume disk space only as needed.
• USN Journal: This feature provides a persistent log of all changes made to files on the volume. This feature is one of the reasons that the Windows 2000 domain controller must use an NTFS 5.0 partition as the system volume.

If you are attempting to set up a dual-boot between Windows NT 4.0 and Windows 2000 or XP, you must have at least Service Pack 4 for Windows NT installed. When installing Windows 2000 or XP, all NTFS partitions are converted to NTFS 5.0. Without Service Pack 4, Windows NT cannot recognize NTFS 5.0, and therefore the computer would be unable to boot to Windows NT. You should also note that the additional capabilities of NTFS 5.0 are available only in Windows 2000 and XP, and these features will not work in Windows NT.

Regarding the performance of FAT and NTFS, FAT performs better on smaller volumes, but NTFS out-performs FAT on larger volumes, beginning around 500MB.

What is the Nations cluster?

The Nations cluster, presently located in Geology 226, originally opened in Student Building 231 in October 1996.

This site consists of 21 Sun Ultra 10 workstations. Each workstation is equipped with 256MB of RAM, a CD-ROM drive, a floppy disk drive, a 9GB hard drive, and 24-bit color graphics on a 21" monitor. The site also has an HP LaserJet 8000 for PostScript printing.

Primarily a development site, the Nations cluster offers C, C++, Pascal, Fortran 77 and 90, and the Java Development Kit.

Other available software includes a suite of Stat/Math and GIS software and a wide variety of public domain packages. Netscape Navigator 4.7 is the standard Web browser.

Note: As with the other Unix systems in the Student Technology Centers, you will need to obtain an account on these computers in order to use them. You need to get a Nations account to use this facility even if you had an account on the old Nations cluster. To request an account, visit the Network ID Services page at:
