SUMMARY
=======

It is possible for a Microsoft Exchange Client computer to connect successfully
to a computer running Microsoft Exchange Server on a local LAN while still
leaving the option for Internet Explorer to Dial When Needed (AutoDial) and not
prompt for a dial-up networking dialog box. The dial-up connection dialog box is
called because of initialization of the TCP/IP protocol on the local machine. It
is possible to connect from a Microsoft Exchange Client to a Microsoft Exchange
Server without using TCP/IP, provided that you can configure both computers to
use a different protocol.

MORE INFORMATION
================

To connect Microsoft Exchange Client to the server without being prompted for a
dial-up connection, perform the following steps:

1. Upgrade Microsoft Exchange Client to Service Pack 2 or later and follow the
  instructions for adding an entry to the Mapiscv.inf:

  Starts

2. Create a new Microsoft Exchange Server profile. For more information on
  creating a profile see "Creating or Deleting a Profile" in the Microsoft
  Exchange Client online help.

3. Install NetBEUI or IPX/SPX on the Microsoft Exchange Client and on the
  computer running Microsoft Exchange Server.

4. Change the RPC_binding_order so TCP/IP is not being called. Change
  RPC_binding_order for all of your clients to include only the entry for
  ncacn_nb_nb or ncacn_spx. The first entry will use NetBIOS rather than
  NetBEUI and should allow you to connect to the server. The second entry will
  use IPX/SPX to connect the client to the server.

Note: NetBEUI is not a routable protocol; IPX/SPX is a routable protocol.

After completing the above steps, you can leave the Dial When Needed option
enabled in Internet Explorer. When you start the Microsoft Exchange Client you
will not be prompted for a dial-up connection.
