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

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

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)
