  http//cc.jlab.org/
• Most references are on the above web page

4
Before we begin

• In Windows, there are several ways to do the same
  thing, so the way I show you may not be the best
  way.

Familiarize yourself with your computer

• System Properties will show you Operating System
  Information, Registration and Computer
  Information
• Right Click My Computer and select Properties.
  Select a General tab.
• Whats my computers name?
• Right Click My Computer and select Properties.
  Depending on your version of Windows, youll see
  a dialog box labeled Full Computer Name either on
  the Computer Name tab or the Network
  Identification tab.
• Whats my IP address?
• Right Click My Network Places and select
  Properties. Open Local Area Connection,
  Properties, then TCP/IP Properties. From here you
  can check or change your IP address and multiple
  other network configuration settings.
• Or open the Command prompt, type ipconfig /all

7
Network ConfigurationStatic vs. DHCP Addresses

• A static IP address is assigned to a specific
  computer and is only intended for use on that
  specific computer. If that computer needs to
  move to a different building, you will need to
  request a new IP. Requesting one is easy see
  http//cc.jlab.org
• A DHCP address (one automatically assigned by the
  JLab servers to PCs configured correctly), should
  only be used for mobile PCs, e.g., laptops or PCs
  used for analysis and moved frequently.

8
Using DHCP

• If you are going to use DHCP, you must follow the
  instructions on http//cc.jlab.org/ DHCP section
• If you dont follow the instruction, your
  computer might be taken out of the network
  automatically.

9
Using wireless

• You must have a wireless card that will support
  128 bit encryption
• In order to use wireless, you need to obtain a
  WEP (Wired Equivalent Privacy) key
• All detailed information is on http//cc.jlab.org/
  , in the Wireless Networking section

10
Being in the JLAB domain

• All Windows machines have to be a member of JLAB
  domain.
• More information on joining the domain is
  available at http//cc.jlab.org/ , in the Windows
  section
• When your machine joins the JLAB domain, your
  login screen should look like this

11
Login Process

• During login, at minimum, your J, K, L and M
  drives will mapped. Open My Computer, those
  drives should be there.
• You will see a black box with unread News. You
  should read all News messages. They contain
  valuable information such as Computer Center
  maintenance days, Outage alerts, and much more.
• If you dont see your mapped drives or News box,
  please call the helpdesk (x7155) or submit a CCPR

12
After joining the domain

• After your machine has joined the domain, the
  following will be installed on your system
  automatically.
• Systems Management Server (SMS) clients
• Norton Anti-Virus software (Norton CE is the only
  approved Anti-Virus software in JLAB, do not
  install different anti-virus software)

13
Automated Updates Windows

• Using SMS, JLab CUE PCs are inventoried for
  hardware/software, installed patches and Service
  Packs.
• SMS, also, gives functionality to remote control
  client systems for troubleshooting
• Using SMS and SUS, new software, patches and
  Service Packs are deployed to JLAB CUE PCs after
  being tested for compatibility with our Windows
  environment.

14
Automated Updates Norton Anti-Virus software

• When your PC is on CUE, you get weekly updates to
  your Norton Anti-Viruss virus definition (more
  often when we receive notification of new
  destructive viruses in the wild).
• CUE PCs are configured to run weekly scans, plus
  real time virus protection (which scans all files
  you open or receive via email) runs constantly.
• If your PC is not on CUE, and you manually
  installed NAV-CE, you are responsible for
  configuring and running updates and real-time
  scans of your local files appropriately.

15
Norton Shield

• If your Norton shield on lower right hand corner
  looks like this
• Good do nothing
• Bad Call Helpdesk
• Very Bad start panic, Call Helpdesk immediately
  

16
Storing Data Files Safely

• Heres my thought Its not a matter of if my
  hard drive will fail me, its a matter of when.
• Files stored on a local hard drive, unless backed
  up on a frequent and regular schedule by a
  reliable method, are not safe. They can be
  destroyed by being overwritten, deleted,
  infected by a virus, or failure of hardware.
• Very few people have the time or are willing to
  make the effort to back up files. We always mean
  to do it but its rarely done.
• Remember - Anything stored on Government
  equipment belongs to government, not you. so,
  its your responsibility to protect.

17
Storing Data Files Safely

• The Computer Center backs up and protects all
  files stored in home (J ), site (K ), apps (L
  ) and group (M ) directories in real time (well,
  almost).
• Within your home directory, there is a
  subdirectory named J\Jde. All files stored in or
  in subdirectories of Jde can only be accessed by
  you.
• IMPORTANT All files outside of JDE can be read
  by Everyone by default.

18
Checking permissions on the fileserver

• Need to use a special tool called Secure Access
• Can be installed from Jlab-Cue/Client Installed
  Programs/
• Demo
• There are few folders on the M drive (group) are
  using NTFS style permissions
• The NTFS style group area is created by special
  request

19
Storing Data Files Safely

• There are two files youll need to copy to your
  home directory fairly often, bookmarks and
  address books. These save locally by default, and
  many users find them personally important.

Shortcut to Recovering Netscape profiles

• For Netscape 7.x
• From Windows Explorer, go to Tools, Folder
  Options, View and select Show hidden files and
  folders
• Go to c\document and setting\Username\Application
  Data\Mozilla\Profiles\Username\xxxxxxxx.slt\
• Delete the Cache directory contents
• Backup the xxxxxxx.slt directory to somewhere
  safe (cd, network, etc.)
• On a new machine, configure your Netscape profile
• Navigate to the xxxxxxx.slt directory on the new
  machine (xxxxxxxx will be different from the
  previous machine)
• Copy the old content of xxxxxxxx.slt to the new
  xxxxxxxx.slt directory
• For Netscape 4.x
• Profile directory will be different
• User Profile directories will be different
  depending on Operating System

21
Checking quota

• Fileservers have a limited amount of disk space,
  so everyone has a disk quota.
• Users need to check their quota before they start
  to copy large volumes of data
• Users can check their quota from
  http//cc.jlab.org/ , in the Quota Check section

22
How to manage your Inbox

• Keep the number of messages small (ideally less
  than 100)

OffLine feature

  your work directories on fileserver (J or M
  drive) directories, available to you while you
  are not connected to the network.

  on the server so that each time you log in and
  out of your computer the files are updated in
  both locations.
