Deployment Guide for the Polycom CX700 IP Phone
Device Update File Storage
During Microsoft Office Communications Server 2007 R2 installation, Device Update Service is automatically installed on all servers running the Web Components Server role. You do not need to plan for additional servers to support Device Update Service.
Device Update Service uses a number of files that must be stored on a file system. The location is different, depending on which edition of Office Communications Server 2007 R2 you are running.
•Microsoft Office Communications Server 2007 R2 Enterprise Edition. Before running the Create Enterprise Pool wizard during deployment, you must create a shared folder for both client and device update files. Device Update Service creates folders within this shared folder in which to store update image files, log files, and configuration files. The shared folder will also be used by Office Communications Server for storing Office Communicator update files. During installation you will need to provide the UNC path of this folder.
For example, if you specified Pool01Data during setup, the path would be:
C:\Pool01Data\ClientUpdateStore\DeviceUpdates
•Microsoft Office Communications Server 2007 R2 Standard Edition. The installer automatically creates the DeviceUpdateFiles folder in the Web Components folder under the Office Communications Server 2007 R2 installation folder on the local computer. This folder is not shared, and it inherits the permissions of the installation folder. Device Update Service creates folders within the DeviceUpdateFiles folder in which to store update image files, log files, and configuration files.
By default:
C:\Program Files\Microsoft Office Communications Server 2007 R2\Web Components\DeviceUpdateFiles\DeviceUpdates
Two virtual directories in Internet Information Services (IIS) refer to these folders:
•The DeviceUpdateFiles_int virtual directory points internal devices to the updates folder.
•The DeviceUpdateFiles_ext virtual directory points external devices to the updates folder.
By default, the built in group Users (for example, Pool01\Users) is issued Read & execute, List folder contents and Read access to the DeviceUpdateFiles_Int and DeviceUpdateFiles_Ext virtual directories (and everything below) in IIS 7.0.For more information, refer to Logs Used for Troubleshooting on page
