XP SP2 en New Mail notifications

[Jacques Schenk]

To allow our Exchange server to send new mail
notifications to our Outlook clients on XP SP2 pc's i need
to allow UDP traffic from our mailserver

How do i do this since i do not know the UDP port used for
this, only it is >1023

on a cisco it would be something like
access-list 101 permit udp <mail server ip> any gt 1023
This would allow all UDP traffic on port 1024 and up from
the mailserver.

You can do the same with XP SP2's firewall, but you'll have to use a BAT file to open that large a range of ports. An alternative is to set the specific UDP port that the client "listens" on.

No way to configure port for UDP new mail notification packets

Note: This only applies to Outlook 2003 clients.
