SUMMARY
If you are an administrator, you can use Microsoft Exchange Chat Service 5.5 to secure a channel to authenticate clients. By default, all channels enable users to enter anonymously.



MORE INFORMATION
The configuration is a two-step process. First, you configure the server, and then you configure each client. To configure the client, you must have Microsoft Chat 2.5. The server configuration is also a two-step process. First, you create a Chat account, and then you set the access levels of the channel to include the Chat account.

How to Create the Chat Account

 * 1) Create a domain global group or local group, and then move the user accounts that you want into this group. The domain global group can be an Active Directory group or a Microsoft Windows NT 4.0 group, and the Exchange Server computer maintains the local group.

NOTE: If you want to add domain accounts individually to the Chat account this step is optional.


 * 1) Start the Chat Service Manager snap-in, right-click Accounts, click New, and then click Create Chat Account.
 * 2) Type a new account name, and then click OK.
 * 3) Right-click the new account name, click New, and then click Add Member.
 * 4) Add the appropriate user or group from step one, and then click OK.

For more information about Chat accounts, refer to Microsoft Chat Online Help:
 * 1) Point to Programs, point to Internet Explorer, click Microsoft Chat.
 * 2) On the Chat toolbar, click Help, and then click Online Support.

How to Set the Access on the Channel

 * 1) Use the Chat Service Manager snap-in to locate the channel properties that you want to limit the client's access to, and then click the Access tab.
 * 2) In the Member account menu, click the name that you created in step three of the &quot;Steps to Create the Chat Account&quot; procedure. The Authenticated clients only check box is enabled automatically.
 * 3) Repeat this procedure for every channel that you want to secure to &quot;Authenticated clients only&quot;.

How to Configure the Chat 2.5 Client

 * 1) Log on to the Chat 2.5 client, and then close the initial Chat Connection page.
 * 2) On the View menu, click Options.
 * 3) Click the Servers tab.
 * 4) Verify the server that you want to connect to is not listed in the &quot;None&quot; network. To do so, click the arrow next to the Network box, and then click .
 * 5) You can add your own network name or use the &quot;None&quot; list.
 * 6) If the server name is not present, add the server name to the Servers box in the network that was chosen.
 * 7) Click the server in the Servers box, and then click IRC username/password.
 * 8) Type the user account you want to connect to that server with.

NOTE: This account must be a member of the domain global group or local group that you created earlier.
 * 1) To connect to the chat server, click Connect on the Room menu.

When you disconnect and reconnect to the Chat server, you receive a prompt to type your credentials. The Chat client is now able enter rooms that have restricted access. If you attempt to connect to a room that you do not have permissions to access, you are not able to view a warning message that indicates that your access has been denied.
