Introduction

Welcome to Library and Technology Services computing facilities. The computers within these facilities are part of network that allows sharing of software, files, and resources such as printers. This guide explains how to use these computers, where to find assistance, and the policies governing their use.

Getting Help

The Help Desk service in the Fairchild-Martindale Library Information Commons (main floor of the Fairchild-Martindale Library) provides a starting point for getting answers to questions about Lehigh libraries, computing, and telecommunications. Help Desk staff respond to inquiries about hardware, software, classroom and lab computing, library collections and services, and phone problems and services. You can reach the help desk by calling 610-758-HELP (4357). The Help Desk is available by email at helpdesk@lehigh.edu or by chat.  More information about the Help Desk is available at: http://www.lehigh.edu/helpdesk  

System Startup

On boot up the computer will display some messages  as it loads into memory.

The system will briefly display a menu with two choices: Press F3 to ghost or wait 5 seconds for normal boot.

If F3 is selected, the reload process will take 30- 40 minutes on a lightly loaded network with a 100Mb connection. Please do not touch the keyboard until the process is completed. It is important to not interrupt this process once it has started.

Ghost Refresh - If you selected Ghost Single Refresh option, the computer will load software to connect to a remote image server and run ghost from this server to restore the hard drive image for this public site computer. As it finishes, it will automatically reboot the computer twice more.

The Ghost refresh resolves many computing issues, including printing problems, software errors, network problems, and more. When the refresh process is complete, all software not on the base image will have been removed from the hard drive (see software section below for an explanation). The computer will continue to start up Windows and then present you with the login screen.

Logging in to the Lehigh Network

Once any LTS public site computer has been started and is ready for use, you will see the instruction to press Ctrl-Alt-Del to Login.

Pressing the Ctrl, Alt, and Del keys will cause a dialog box similar to this to appear on the screen.

 

To log into the computer, enter your user name and password in the appropriate fields; press the Tab key to move between fields. Make sure "Log on to: AD" below the password field is visible.  If it says something like "Log on to: PS-xxxxx" then you'll need to enter your username as "ad\username" in the username field.  If it says "Log on to: FSxxxxxx" then it's a faculty/staff machine (you may still be able to login using ad\username if you have permission).  When you are finished using a computer at an LTS public site, REMEMBER TO LOG OUT. If you fail to log out, someone could access your email, coursework, or academic records. To log out, click on Start and choose Log Off from the Start Menu.  Make sure you are completely logged out before you leave the PC.  Often the logout process with require user confirmation or the process could hang.  You are not logged out until the PC returns to the main Logon screen.


Locked Workstation

If another user has been logged into the workstation and left without logging out, the computer will display the message "press ctrl + alt + delete to unlock this computer"and below that in small type it says who's logged on. If you are not the user who is logged in you will need to turn the PC off and then on again.  Hold the On/Off button down for at least five seconds or until you see the light behind the button disappear. Then, turn  the PC back on, and log in as usual.

Windows 7 Desktop

The Windows desktop contains several items. Along the right-hand side are:

At the bottom of your screen is the taskbar which includes the Start button at one end and the system clock at the other.

Other icons, such as the Firefox, IE, Chrome and Word quick launch and the Symantec Antivirus active protection logo, may appear in the taskbar.

All software can be started from the Start button's All Programs menu.

Password Protected Screensaver

In order to protect users' confidential data, a password-protected screen saver has been implemented at the public sites and computing classrooms. The timeout for lecture hall instructors stations is 2 hours, for all other public site machines it is 10 minutes.
Screen saver can be activated by pressing the  "Windows + L" keys on the keyboard. The original user can log back into the computer with the Lehigh password. If the original user has left the PC without logging off, the next user will need to shut the PC down and restart it.

Exiting the Lehigh Network

Logging Out of the Lehigh Network

When you are finished using a computer at an LTS public site, REMEMBER TO LOG OUT. If you fail to log out, someone could access your email, coursework, or academic records.

 To log out, click on Start and choose Log Off from the Start Menu.  Make sure you are completely logged out before you leave the PC.  Often the logout process will require user confirmation or the process could hang.  You are not logged out until the PC returns to the main Logon screen.

Antivirus & Security

Invasive software (described by terms such as computer viruses, worms, and Trojan programs) can be spread around the world in a matter of days; anyone connected to the Internet can be at risk from invasive software. All LTS public site computers have Symantec Endpoint Protection (SEP) installed. You can also minimize risks from invasive software.

Accessing Email

There are two primary methods for accessing your Lehigh electronic mail from the public sites.

More information about using mail can be found on the web page: http://www.lehigh.edu/computing/accounts.html

PC and Linux Workstation Site Information

Detailed public site information is available at http://www.lehigh.edu/classrooms. The information available includes site usage information, site hours, hardware available, room reservation contacts, departmental supplies contacts, site types and news. Site hours for the EWFM Computing Center, the EWFM Library and Linderman Library may also be obtained by calling 610-758-2828.

Linux Workstations

In addition to the computers at distributed sites, LTS maintains more than 20 Dell Precision Linux workstations located in 4 public sites on campus . They are also connected to the campus backbone and the central file space; as a result, a single user can perform high intensity computing using the resources of several workstations simultaneously.

Questions about availability of software for Linux workstations and compute server should be directed to Mary Jo Schulze, 610-758-4590. Software function questions should be directed to the Helpdesk or your computing consultant.

Windows Software

Basics

To begin using any software, click on the Start button, then go to All Programs and find the folder for the software. At minimum, the following software is available: Adobe Reader, Apple itunes, Symantec Endpoint protection (SEP), Microsoft Office (Word, Excel, PowerPoint, Access), notepad ++, Internet Explorer, SSH Secure Shell, Firefox, Thunderbird, along with Quick time, VLC and Paint.NET. (Other utility programs are under Accessories.) These programs are at all computing facilities and available after login. LTS refers to this base set of programs as the base image. Performing a complete software reload provides a new copy of this base image to the computer's hard drive.

Installing Software

The Lehigh Software link on the Desktop allows the installation of software that is not loaded by default. Choose Install Software from the desktop link on the right hand side to get a list of software.

(The list of software available on the public sites differs slightly from that available in campus offices or on WIRED computers. This page lists around 100 software packages licensed by Lehigh and distributed over the campus network. This software can be installed only on campus. The right-hand column indicates restrictions).

Click on a software title for the description/installation page, then click on the install button.

In the File Download window that comes up, click the button Open.

You will be asked whether you are sure you want to play this script; click 'Yes'. Wait for the installation to finish. When you receive a message that the installation is complete click OK.

You can begin using the software by the same process as above (click on Start, then All Programs). Software that has been installed this way will be removed from the computer when the next Ghost Refresh is performed.

Can I install my own software?

You cannot install personal software on public site PCs. If you try to install personal software you will likely get  a message that you don’t have administrative rights to do this.

Availability

If the program has limited availability (e.g., it is only available for use in Packard Lab room 502), this information will appear in the 'Restrictions' column of the Install Software listing. Although you will be able to install the software, you will not be able to run it – a 'Key Server' message "cannot grant you permission to run this program" will appear. The limited availability of software can usually be attributed to terms contained in the software’s license agreement.

Some software is acquired in limited quantities (e.g., 25 licenses). If the maximum number of copies of the program are already is use by other people on the network, you are presented with a message "all licenses are checked out, Key Server will notify you when a license is available." You are then given an option to be placed on a waiting list. LTS strives to have a sufficient number of licenses available so, hopefully, you will not see this message often.

Computing software availability

Complete information about what software packages LTS provides is available on Lehigh’s Web page at the following URL: http://www.lehigh.edu/computing/software/software.html. There is a listing of site and volume licensed software, software listed by categories (e.g., word processors), and an alphabetical listing. Questions regarding PC and Mac software available at the public computing sites and classrooms can be directed to the software librarian at 610-758-6247. Questions about software functionality should be directed to the Helpdesk or a computing consultant.

Library Electronic Resources

From the Library and Technology Services page off LU's home page, you can go to the Library page available at: http://www.lehigh.edu/library/. Accessible from this page are ASA (the library's catalog), abstract/index services and full text databases, electronic journals, service requests and guides to using subject resources.

Files & Printing

1) I just saved my PC file and now I can't remember where I put it.

The location of the file depends on what program you are using.

Warning: Before saving a file, make sure that there is enough space for it on the location or device you are using; attempting to save to a drive with insufficient space can result in loss of the file. Saving to your H: drive and then copying to a flash drive is recommended.

A quick tip: Always select "Save As..." from the program's File menu when saving a file. This will allow you to not only designate where to save the file, but also what format to save it in. LTS  recommends saving your files to your H: drive while you are working on them, and transporting copies via a flash drive. (see 3)  Where should I put my files?)

If the file is not immediately apparent in the "My Documents" or "My Files" folders, you have two options:

2) Searching for PC files

Using Search:

From the Start menu, choose Search programs and files.

 

3) Where should I put my files?

Storage areas for files include:

4) If I accidentally deleted a file, is there any way to get it back?

To retrieve data a file from the H: or I: drive, follow Shadow copy instructions:

http://www.lehigh.edu/helpdesk/docs/shadow/copy.html

To request a file reload from other servers, contact the Help Desk.

Computing Systems Backup Schedule

Mail Server

Full backups Monday, Wednesday, and Friday, starting at 5:00pm

HPC Servers

HPC Server backups are run on a Daily, Weekly, and Monthly schedule. All backups start at midnight.

AFS Servers

All files are copied to tape every Monday through Sunday beginning at 5:00 a.m. (Note that a complete copy of your AFS space is backed up to the yesterday directory (check /home/{userid}/yesterday) at 5am every day; you can copy files from there yourself.)

Local Area Network (H & I Drive) Servers

All files are copied to tape every Friday beginning at 8 p.m. Files that have been modified are copied to tape (incremental backups) every Monday, Tuesday, Wednesday, and Thursday beginning at 8 p.m.


5)  Can I print multiple copies of my paper?

No, you may only print one copy. If you need to make duplicates, there are copy machines in several areas across campus. Example: EWFM 449, Linderman first floor rotunda, Rauch Copy Center etc.

6) I clicked on "Print" but my paper isn't printing. What's going on?

[What about t-shooting steps like checking the print queue, looking for errors] Long print jobs and multiple copies of the same job can cause errors and loss of data.  During heavy usage it may take a while for the printer to get to your print request.

7) How do I cancel printing of a document that has already been sent to the printer?

In the Start menu, select Printers and Faxes. Double-click on the printer to which you sent your job. If the job is still displayed, you can select it and click Cancel to remove it. If the job is big and on the printer, you can also cancel it with the cancel job button on the printer (red x). 

8) The printer says it's out of toner or paper. Where do I get more?

A list of site contacts is available at: http://www.lehigh.edu/classrooms/sitecontact.html. Contact the Operation/Supplies Contact listed for the specific site.

9) Where can I place documents I want to share with other students or staff?

Anything saved to the H:\public directory on your Lehigh Network space is visible and can be downloaded by everyone."

H drive is accessed through Start- Computer- H drive.

You can also share files to specific people with Google Apps.  Use the link on the desktop to login and upload files to documents.

 

For Faculty Using Classrooms

Classroom Support

LTS provides the highest priority response to faculty experiencing technology problems while teaching a Lehigh class during the hours of Monday through Friday 7 a.m. - 4:30 p.m. While all problems may not be resolved on the spot, a Technology Installation and Maintenance Services (TIMS) technician will be dispatched as soon as possible. If quick repairs cannot be made, or in the case of a prolonged outage, Instructional Technology Support Services (ITSS) will contact faculty using the affected room to arrange for loaner equipment or class relocation until repairs can be completed. Contact the LTS Help Desk at x8HELP (84357) to report technical difficulties and expedite service.

While classroom technology systems are inspected and tested regularly, we rely on our clients to report technical problems, missing equipment, burned out overhead bulbs, etc. To enable LTS to provide prompt service, please report all difficulties as soon as possible to the Help Desk. An email distribution list is maintained for all technology rooms to alert clients to any problems that develop during the course of the semester. Contact Facilities Services at x83941 or x83940 to report facility problems such as broken furniture, HVAC problems, burned out lights, cleaning issues, etc.

Using the DVD Player:

To use a DVD, turn on the computer, log in, open the drive and insert the disk. At the prompt, double click the "Play movie using WinDVD" icon. Click the maximize icon in the display window to fill the screen. A right mouse click displays the text controls, and a double click returns to the smaller display with a control panel.

Classroom Training

Instructions for use of classroom technology are posted in each room. They are also available on the web by clicking on the classroom in the classrooms listing at http://www.lehigh.edu/classrooms. Instructional Technology Support Services (ITSS) may be contacted at 610-758-3059 to arrange for training for any technology classroom.

Equipment delivery in support of classes

Instructional Technology Support Services (ITSS) may be contacted at 610-758-3059 to arrange for delivery of projection technology in support of Registrar scheduled classes. Overhead, slide or video projectors can be delivered as needed. Microphones are also available for selected rooms. These items are also available for pickup in the Media Center in Fairchild-Martindale Library. It is strongly recommended that faculty requiring technology support for classes on a regular basis arrange with the Registrar for assignment to a room where the needed equipment is permanently installed.  

Registrar and reservations for classrooms

Any use of classrooms outside of scheduled class time must be reserved through the Office of the Registrar. This is very important to avoid scheduling conflicts.

It is strongly recommended faculty insure that specific technology needs are included on the "line schedule", which is the form used by the Registrar to designate which courses will be taught each semester. This information will enable the Registrar to schedule your course in an appropriate room. There is a column on the line schedule titled "miscellaneous" where technology requirements should be added. The line schedule is sent to departments in August, November, and December. Please note that any changes to the master course schedule should include equipment requests.
