  • Home directories
  • Migration out of Novell Netware
  • Migration out of NT4
  • Tools
  • Application distribution
  • Next Steps

3
Windows 2000 Pilot Experience
  • 150 systems
  • 30 Windows 2000 Servers
  • 130 Windows 2000 Professional
  • 2.5 of expected scope
  • Variety of users ?
  • but mainly volunteers ?
  • Variety of platforms
  • Laptops (15)
  • 90-800Mhz, 48-gt512 MB

4
General problems encountered
  • DFS FRS on large volumes sometime fails
  • Maybe due to staging space limitations
  • Decided to switch FRS off for Home dirs.
  • SMS software metering sometimes fail
  • Will see if future versions solve this
  • DNS integration with Unix bind was not easy
  • Server backup SW long to arrive
  • Some problems with portable and PNP/Modem/APM
    have been observed
  • Cleared by a reboot
  • Support for some devices is still flaky
  • E.g. GSM, HP consumer printers

Overall impression positive
5
Windows 2000 on Portables
  • Benefits
  • All your documents can be made available for
    offline use
  • Hibernate/Standby support
  • DHCP
  • PnP
  • Resilient to network/server failures
  • Problems
  • Some PnP problems appearing occasionally

WINDFS02

Users\a\adimeg
WINEP01
Users\a\azu

Users\z
  • Initial pilot proposal based on a divisional
    structure

But
9
Problems with this approach
  • MS recommends maximum 1000 DFS mount points
  • There are more than 8000 users
  • We ran into the limit where no more links could
    be created (September 2000)
  • Automatic creation of users gets complicated
  • A lookup on every div is necessary
  • Users change from div to div

So alphabetic ordering was implemented
11
Architecture limitation ?
  • With this approach, all accounts with the same
    initial letter must be on the same physical
    server
  • All home directories must be hosted in 26 servers
    maximum
  • However
  • Better that divisional approach where all home
    dir had to be hosted in max 11 servers
  • In all cases, project space can be used to
    offload home directory servers if necessary
  • With present technology, all home directories
    could be hosted in 4 servers there is lot of
    space for growth (especially because server
    technology evolves very fast)

Applications
Systems
13
Macintosh support
  • Should we offer Appleshare services from DFS ?
  • File services for the Mac are one generation
    behind services for Win
  • Can compromise the stability of the DFS service
    (as it did with Novell in the past)
  • Only for a minority of users
  • Still unclear if the Mac will be a supported
    platform at CERN

14
Outline
  • Pilot experience
  • Plans for production services
  • Home directories
  • Migration out of Novell Netware
  • Migration out of NT4
  • Tools
  • Application distribution
  • Next Steps

15
NetWare Migration to W2000
  • A nightmare, largely underestimated
  • Multiple name spaces
  • Support for Macintosh
  • Historical situation grown from 1990
  • Large number of accounts (gt8000)
  • Large number of groups (gt800)
  • Large number of (old) files (10 M)
  • Complex file protection scheme
  • Not directly mappable to W2K

16
Scenario
  • Migrate NW file systems to NTFS5
  • CERN NT domain (not W2K pilot)
  • Keep UNC paths unchanged (user transparent)
  • No NT4 servers
  • Successful reliability and performance results
    win2000
  • Better ACL mappings (inheritance, special rights)
  • Name spaces
  • DOS-OS2 (long names), MAC, NFS
  • Different server types
  • Workgroup servers, MAC only servers, NICE
    application servers, divisional servers, home
    directory servers

17
Technical Problems
  • MAC name space
  • NW provides APIs to extract AFP resources (icons,
    MAC name), but no Win32 API to write these back
    to a NTFS server -gt Use a Mac to transfer files
  • The Mac does not copy ACL and all security
    related information
  • NFS name space
  • No solution for automated file ownership/rights
    migration

18
Migration sequence
Netware server
W2K server
19
Migration sequence
NTMigrate (Win2000)
1 - Get a PC (NT4 32bit NW client)
5 Convert users, groups and file rights
4 Generate Trustee NW Group member files
5 Create groups and add members
2 - Create Directory structure file DOS,
AFP name space (NDSDump)
6 Set ACLs on directories
7 - Get a Macintosh
8 Copy files using DirStruct file (speed) 9
Rename directories DOS -gt Mac name
Netware server
W2K server
3 - Create Directories on target server

NetWare Servers migration
21
Problems Encountered ?
  • Client for MS sometimes not correctly configured
  • Manual fix
  • Netware/NT Password not synchronized
  • Manual / automated fix
  • ftp access syntax changed
  • New syntax to learn, scripts to modify
  • Manual drive mappings
  • Needs to be recreated
  • No root mapping
  • Kludge exist on NT nothing on W95
  • Trustee manager not available
  • Trustee manager written
  • Disconnected portable take time to logon
  • Eject PCMCIA Ethernet adapter
  • Home Directories are browsable
  • Feature, similar to AFS

27
Application Concurrent Usage
28
Managed Applications
  • Part of OS
  • Internet Explorer
  • Assigned to Computer (using MSI)
  • MS Office 2000
  • Access, Excel, FrontPage, Outlook, PowerPoint,
    Word
  • Acrobat Reader, Printing Package, Phone Book,
    Winzip, anti virus, and other tools
  • Published to User (using MSI or ZAP)
  • MS Project, MS Publisher
  • Remedy
  • Exceed

All most used functionalities are provided
29
Application Deployment
  • Still unclear to what extent SMS will be used
  • We are trying to deploy using mainly MSI and ZAP
    files
  • In order to use ZAP files, the Administrators
    local group has to be managed

30
Comparing SMS 2.0 and Win 2000
Windows 2000 SMS 2.0
Application deployment ? ?
New OS deployment ?
OS update deployment ?
User settings management ?
User data management ?
Hardware / software inventory ?
Remote tools ?
Software metering ?
Network analysis / diagnostics ?
Health monitoring ?
Only overlap is in software deployment!
31
Systems Management Server
Roles Benefit Impact on Privacy
Discovery Asset Management None. Similar to network pages.
Distribute Software Manage Service Packs/Software Limited. Just installs packages and keep track of its success.
Hardware Inventory Asset Management /Problem Determination Can see what Hardware is and when it has been changed.
Software Inventory Asset Management Can see what software has been installed.
Remote Tools Helpdesk/Problem determination Can see what user does. Can launch a command. Monitored. But to be used by contractors.
License Metering Software usage/License estimation/License enforcement Can see what software has been used. Similar to NICE.
32
SMS Questions
  • Are there any privacy issues?
  • Do we have to restrict access to these tools? To
    whom?
  • Do we have to include special clauses in
    outsourcing contracts ?
  • Do we have to have our own staff to sign
    something ? (cf. HR data).
  • How do we publicize this ?

33
Few words on an hot topic
  • Netscape is currently the most used app at CERN
  • But we see a dark future
  • Netscape 4.7 has not been made available (as a
    managed app.) in the pilot
  • No SMS/MSI install available
  • No CERN customization available
  • Repackaging risk to be difficult
  • IE 5.x integrated in the OS
  • Outlook now part of Office (with MSI)

34
Current Proposal
(under discussion)
  • Recommend Internet Explorer and Outlook 2000 as
    the browser and mail client for Windows 2000
  • Apparently stable
  • No CERN specials anymore
  • Bookmarks and Address Books can be imported
  • IMAP mails structure unchanged
  • Deployment of collaborative tools possible
    (calendaring, groupware, video conferencing, )

35
W2KMTF
  • The current question is now
  • How to proceed with the next steps, I.e. how do
    we go from the current NICE 95/NT to NICE 2000
    and what timescale ?
  • Applications many of them, overlapping
    functionality, support not always clear, work
    needed to repackage ?
  • At what speed are the divisions/experiments ready
    to migrate ?
  • What are the show stoppers ?
  • A working group has been setup
  • Windows 2000 Migration Task Force
  • First meeting scheduled the 7th of November
  • More than 30 participants

36
Outline
  • Pilot experience
  • Plans for production services

  • Next Steps

37
Next Steps
  • Define automated installation procedures
  • Unattended W2K setup assigned applications
  • sysprep / disk image for new PCs portables
  • Develop missing tools
  • Repackage missing applications
  • Once the application set has been decided
  • Customize mail client for CERN environment
  • And finally, start migrating client computers
  • 4000 PCs, 2 hrs/PC ? 5 manyears
