256986 Description of the Microsoft Windows Registry

SYMPTOMS

If you use Network Address Translation (NAT), you may not receive new e-mail notifications in Outlook 2000.

CAUSE

This problem can occur in an NAT environment because Outlook 2000 never receives the universal datagram packets (UDP packets) that the Microsoft Exchange Server computer sends, and you cannot route the UDP packets to a computer that is running Outlook 2000.

The computer that is running Outlook 2000 returns to polling the Exchange Server computer for new e-mail messages by using the Remote Procedure Call (RPC) to work around this problem. However, a logic error exists with the Exchange Server computer, and it does not reply to the polling request.

RESOLUTION

To resolve this problem, configure Outlook 2000 to use polling instead of UDP to receive new e-mail notifications. To do this, use the following steps:
  1. Apply the hotfix to the computer that is running Outlook 2000.
  2. Manually add registry entries.

How to Use the Hotfix

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing.

STATUS

MORE INFORMATION

Outlook 2000 uses both UDP and polling to notify you of new e-mail messages.

With UDP, Outlook 2000 sends the server the client's Internet Protocol (IP) address and notifies the server to send the UDP when there are e-mail messages waiting on the server.

The polling mechanism occurs when Outlook 2000 starts a thread that requests information from the server every 60 seconds with the remote procedure call (RPC), by default, for any outstanding e-mail messages.

The default preference for e-mail notification in Outlook 2000 is UDP, and if that fails, Outlook 2000 uses polling. The registry value described earlier in this article defines whether or not to use polling as the default for new e-mail notification. The value of 1 indicates that polling is used as the default by Outlook 2000 and that UDP will not be used. The default polling time is 60 seconds and is set at the Exchange Server.
