The Domain DESYNT • Single Domain spanning Hamburg and Zeuthen • ~2000 registered users in 55 groups • Groups are more or less based on DESY administrative structure • Group administrators are responsible for • Configuration and installation • Support for the users • Account maintenance • Computer accounts • About 1400 active nodes • ~1050 workstations online per day (900 in parallel) • Growth rate is flatting out DESY WNT-PG Helga Schwendicke

  11. Management • Application support • NetInstall V4 in production since May 1998 • About 50 applications in 13 software groups • Migration to Version 5  Ch. Trachimow: “Application support” • Administrative tasks • Web Based Domain Management WBDM  H. Bartels: “NT based WebServices & Web based domain management” • Scripting  Ch. Trachimow: “ A scripting host for domain automation tasks” • Not only a replacement of the TEM – more functionality DESY WNT-PG Helga Schwendicke

AntiVirusSoftware • VirusScan V4.04 from Network Associates • Start with an Antivirus test domain in June • Scanning on access (default) • Private scan schedules are possible • Management Edition • Real time software distribution system • Doesn’t meet our demands • Only one database • Frequently disk access – Network Monitor Agent (10 sec.) • API’s unknown and not documented • no script support for management possible • Messages to GA’s and AV Admin when virus found • First distribution via NetInstall package DESY WNT-PG Helga Schwendicke

  13. Outlook • Migration to NetInstall V5 • Terminal Server investigations • Configuration • Scalability and Load balancing • Access protocols (RDP, ICA, X) • Groupware • Windows 2000 • Still at the very beginning – no migration concept • Small NT test domain with Beta3 RC1 • IP test domain with DDNS between Hamburg and Zeuthen(Bind8 server – waiting for tests) DESY WNT-PG Helga Schwendicke
