Installing OCS 2007 R2 on Windows 2008 R2

#OCS #WindowsServer #Powershell

Here is a tip for if you want to speed up the process of installing OCS on a Windows 2008 R2 server.

The installation wizard and guide is made for previous OS's, and is not capable of detecting or installing all of the features you need (.net framework beeing one of them). Also, I realized all the tech blogs I came across on google suggested to use the servermanagercmd.exe to add some of the prerequisites. servermanagercmd is depreciated, and I suggest you use Powershell in Windows 2008 R2.

So, before even thinking of starting the OCS setup, you should concider running the following commands in powershell (as administrator):

import-module servermanager
web-windows-auth,web-mgmt-compat,web-mgmt-console,web-http-logging,msmq-server,msmq-directory,rsat-addc,was-process-model,was-config-apis,NET-Framework-Core,Desktop-Experience -restart

So far, so good, but now I,m stuck with a new error: 0x80070534 "No mapping betweein account names and security IDs was done. This error is registered on the "setting NTFS rights" section in the error report. Anyone got an Idea?
