11. CERN - European Organization for Nuclear Research Frédéric Hemmer/ITFOCUS - December 6, 200111 Applications Over 70 applications from many vendors –Including Autodesk, PCAD, Labview, etc… –Support model documented at http://w2kmtf.web/w2kmtf/Applications.htm –Managed thru a mixture of Group Policy SMS VB Scripting –Simple Applications can be integrated in matters of hours –Complex applications require several weeks Testing, upgrade options Example: HummingBird Exceed, Autodesk, Office

16. CERN - European Organization for Nuclear Research Some Difficulties

17. CERN - European Organization for Nuclear Research Frédéric Hemmer/ITFOCUS - December 6, 200117 Difficulties (I) Under configured/unsupported hardware NT4 – Windows 2000 coexistence –Roaming profiles Can be disabled –NTFS permissions Use trustee manager Applications accessing directly hardware –Scanners; CD Writers; etc. Stability –People do not logoff anymore What are logon/logoff scripts useful for? –Offline folders sometimes confusing I’ve lost half of my folders ! Training obviously needed Outlook not the perfect tool –Needed at least as Schedule+ replacement –Parameterization very important

18. CERN - European Organization for Nuclear Research Frédéric Hemmer/ITFOCUS - December 6, 200118 Difficulties (II) Applications –Some applications badly written Typically uses.ini files Requires (sometimes) tricky scripting/VB –Unavailability of MSI Workaround by using VBScript ZAP files calling setup –Coexistence with other tools E.g. Oracle, AFS MS Group Policy –Not very flexible E.g. Office 2000 security patch requires complete redeployment Leaving the domain removes Office SMS –Software metering does not scale Handling of tricky PnP problems –E.g. Siemens Lifebook does not see the network adapter when booted on batteries –Undocking from port replicator cannot be done while in standby or hibernation MS handling of (security) patches is targeted at the masses, not in a corporate environment –E.g. numbering does not change for different revision of the same patch

22. CERN - European Organization for Nuclear Research Frédéric Hemmer/ITFOCUS - December 6, 200122 Divisional evolution November,22 2001 39% of 5275 machines are Windows 2000 1600

23. CERN - European Organization for Nuclear Research Frédéric Hemmer/ITFOCUS - December 6, 200123 Future of NICE 95/NT – June ’01 Proposal Freeze NICE 95/NT by end of 2001 –Still installable by floppy –No new applications, functionality, etc Stop (central) support by mid 2002 –No answers from helpdesk –Solution to problems: upgrade to W2K –Still installable by floppy Ensure servers are running until end of 2002 –NICE 95/NT environment still working NICE 95/NT for new PC’s ? –Unlikely new PC’s will be able to run Windows 95 –We still have a stock of Windows 95 capable PC’s

24. CERN - European Organization for Nuclear Research Frédéric Hemmer/ITFOCUS - December 6, 200124 Summary People usually not unhappy happy with NICE 2000 –Especially compared to NICE 95 –Mobile computing is now easier Windows 2000 is maybe not perfect –But every time we looked a a problem, there was a solution –There are numerous tools and interfaces available –And … we now have a PSS license ! Will not be easy to keep the momentum –But essential in order to reduce support costs –E.g. Coexistence, security fixes, hardware support CERN seems more advanced than other HEP labs in terms of W2K deployment, especially on the server side All this has only be possible because of your collaboration – thank you !
