The information in this article applies to:

- Microsoft Exchange Windows 3.x client, versions 4.0, 5.0 
- Microsoft Exchange Windows NT client, versions 4.0, 5.0 
- Microsoft Exchange Windows 95/98 client, versions 4.0, 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you start a Microsoft Exchange Windows client, the main application window
may take a relatively long time to load after the startup screen appears.

RESOLUTION
==========

You can significantly improve startup time by correctly configuring the remote
procedure call (RPC) binding order on the computer running the Exchange client.
For additional informationabout the steps necessary to modify the RPC binding
order, click the article number below to view the article in the Microsoft

  Q163576 XGEN: Changing the RPC Binding Order

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

When the Exchange client starts up, it uses the first protocol in the RPC
binding order to attempt to communicate with the Microsoft Exchange Server
computer. If this attempt is unsuccessful, the Exchange client then uses the
next protocol in the binding order, and so on, until it has established
communication with the server or it has run out of protocols. In the latter
case, an error message is displayed and the user is asked if he or she would
like to work offline.

Hence, if the protocol installed on the client machine is at the top of the
binding order, the client establishes communication with the server in the first
attempt and does not have to time out and go down the binding order. This can
significantly reduce the startup time.


NOTE: The information in this article only applies to setting the RPC binding
order for the 16-bit Windows, Windows NT, and Windows 95 clients. It does not
apply to the MS-DOS client, because a different setup method is employed.
