Configuring File Transfer Filtering

  • Artigo

Tópico modificado em: 2009-03-02

Filter transfer filtering affects both instant messages and conferencing meetings. For meetings, these settings affect both the handout feature in the Office Live Meeting 2007 client and multimedia playback features.

Dica

The Intelligent IM Filter increases the amount of CPU resources required to process URLs in a message. This increase in CPU demand also affects the performance of Office Communications Server 2007 R2 itself.

Use the File Transfer Filter tab and the procedure in this section to configure filtering options for file transfers.

Dica

Office Communicator also offers file transfer setting options. This server-side option is offered in addition to the client-side controls available in Office Communicator.

Use the Enable file transfer filtering option to filter file transfers during instant message conversations, when you are using the handout feature in the Office Live Meeting 2007 client, and for multimedia playback features for all file types. If you chose to use the Enable file transfer filtering option, you also need to choose one of the following options:

  • Block all file extensions. All instant messages that contain file transfer requests are dropped by the server, and an error message is returned to the sender of the request. The handout feature in the Office Live Meeting 2007 client is disabled.
  • Block only file extensions in the list below. You specify which file transfer requests are filtered by the server by specifying a list of file extensions to block. Entries in the list can contain all standard characters, but not the wildcard character (*). In the Office Live Meeting 2007 client, the handout feature is enabled but any file with this extension cannot be uploaded or downloaded. URL filtering uses this list to block active hyperlinks that contain any of these file extensions if you select the Block all intranet and Internet hyperlinks that contain any of the file extensions defined on the File Transfer Filter tab check box on the URL Filter tab. By default, URL filtering is configured to block these file extensions in active hyperlinks.

Importante

Filtering of file extensions is limited to standard file names. Filtering may not work with file extensions embedded in other names.

To configure a file transfer filter

  1. Open Office Communications Server 2007 R2.

  2. In the console tree, do one of the following:

    • To configure client version filtering for an Enterprise pool, expand Enterprise pools, right-click the pool name, point to Filtering Tools, and then click Intelligent Instant Message Filter.
    • To configure client version filtering for a Standard Edition server, expand Standard Edition servers, right-click the name of the pool, point to Filtering Tools, and then click Intelligent Instant Message Filter.

  3. On the File Transfer Filter tab, configure the appropriate settings.
