Last week I had the task to setup a Lync server on our Hyper-V cluster. Its a bit hard do work on everything without administrator passwords because I need Amit to login everything. But besides this the installation had some problems because some services don`t start and the installer can`t install features itself. I got quite far. But before we can start the installation of the service itself we have to install certificates. Oddly there was a warning if we install one of the certificates that it could create errors on out exchange and sharepoint. So we have to clear that issue with the head system engineer.
