Configure Bits Using Server Manager and IIS7

When transferring delta information from the server to the client, you may have the Web Service use either Background Intelligent Transmission Service (Bits) or UncCopy. Bits is a Microsoft technology that is used to transmit the delta file to the client. If the transfer is interrupted, the Bits technology picks up where it left off and completes the transfer. If you wish to use bits, the Replication Server must use IIS6 or later. UncCopy moves the delta file to the client. However, should the transmission be interrupted, the delta will NOT be copied to the client and the update will have to be performed again. UncCopy may be used with a server running IIS5 or IIS6.

If you choose to use UncCopy to transfer delta files, no further web configuration is necessary. If you wish to use Bits to transfer delta files from the server to the client, you must perform the following additional configuration.

Open the Server Manager, select Features and click Add Features. The Add Features wizard opens. In the wizard, select .Net Framework 3.0 Features and BITS Server Extensions. Continue until you complete the installation.
Open the Internet Information Services (IIS) Manager.
Under Sites, select Default (or Default Web Site).
In the next pane select BITS Uploads in the Other category (at the bottom). In the Actions pane click Open Feature.
When the BITS Uploads feature opens select Allow clients to upload files. Use the default settings or use custom settings if necessary.
In the Actions pane, click Apply.
Close the Computer Management window.
