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
