We are using MAK keys to install the software, but when the system is up-and-running it still needs activation. I heard that we will be using KMS servers for this. I 've read the microsoft documentation about this but did not quit understand the details. I think I need to reread the article once (or twice) before i will... My primary concern untill now was the setup of a flexible deploymentprocedure that would fit our current needs and environment. I managed to build a procedure with uses 1 (altiris) job, 1 -database driven- unattend.xml template, 1 wim file, and 1 WinPE (32 bit) PXE OS image. The engineer only needs to supply a single abbreviation (out of 32 : core/gui | 32/64 bit | web/standard/enterprise/datacenter | SP0/SP1) for the wanted OS variant. This procedure is prepared to be used in a number of different environments of witch the properties (DNS servers, ad name, target ou, WSUS server etc) and their possible values are to be stored in a separate database table. Based on the (standardized) servername, the right environment is chosen. I was afraid the separate keys (and what it might be that made MS decide to choose this solution) would have an impact on the deployment, but that was not the case as far as I noticed.
