SUMMARY
This article discusses how to configure Exchange 2000 Conferencing Server for Internet attendees. Requirements for this type of accessibility include a resource that includes both default Conference Technology Providers, and H.323 fallback. This article assumes that you have already installed and configured Exchange 2000 Conferencing Server, and that it is functioning correctly.

NOTE: You must configure more than one Microsoft Windows 2000 site before the Conference Management Service can distinguish users as either connecting locally, or from the Internet. If you do not configure more than one site, all users appear to come from the default, Windows 2000 site. You can configure more than one Windows 2000 site by creating a fictitious Windows 2000 site in the Windows 2000 Sites and Services Microsoft Management Console (MMC) snap-in, and then assigning it a fictitious IP address (not a range) with /32 subnet mask.

IMPORTANT: If you create a dummy site to enable CMS to distinguish Internet users from local users, and Exchange 2000 is installed on a member server, you also need to define a subnet for the default site and reinstall Exchange Conferencing Server.



MORE INFORMATION
To provide accessibility to online conferences for Internet attendees, follow these steps:
 * 1) Click Start, click Programs, click Microsoft Exchange, and then click Conferencing Manager.
 * 2) Right-click  , which is the name of your conferencing site, and then click Properties.
 * 3) Click the Resources tab, and then create a resource mailbox that includes both Conference Technology Providers (such as the Data Conferencing Provider, and the Video Conferencing Provider).
 * 4) When you add the Video Conferencing Provider, you must enable H.323 fallback by clicking to select the Enable H.323 Data Provider fallback for Audio/Video Conferences check box.
 * 5) Click the Data Conferencing Provider node under  .
 * 6) Right-click T.120 MCU Server in the Results pane, and then click Properties.
 * 7) On the General tab, click to select the Accept client connections from the Internet check box.
 * 8) In the Use network name field for the Accept client connections from the Internet check box, enter the Fully Qualified Domain Name (FQDN) of the T.120 MCU Server (The FQDN cannot be longer than 32 characters).

Allow enough time for replication if you have multiple domain controllers and/or domains in your topology.

IMPORTANT: If you are modifying the Internet &quot;Use network name&quot; field from a host name to a FQDN, you need to either restart the server or use the Dscflush utility from the Exchange 2000 Resource Kit to clear the DS cache. Also, allow enough time for replication if you have multiple domain controllers and/or domains in your organization.

When you join an online conference across the Internet, you must enter the FQDN of the MCU computer in your browser's address field.

If you create the fictitious site and IP subnet for Conferencing server you should also define a subnet for the default site where the initial Exchange 2000 server resides.
