IIS Requirements for Enterprise Pools and Standard Edition Servers

For both Standard Edition servers and Enterprise pools, the Office Communications Server 2007 R2 installer creates virtual directories in IIS for the following purposes:

To enable users to download files from the Address Book Service
To enable computer-based clients, such as Office Communicator, to obtain updates
To enable Web conferencing
To enable users to download meeting content
To enable unified communications (UC) devices to connect to Device Update Serviceand obtain updates
To enable users to expand distribution groups
To enable phone conferencing
To enable response group features

The following table lists the URIs for the virtual directories for internal access and the file system resources to which they refer. The file system folders to which the virtual directories refer are described in Storage Requirements.
