Hi Tim, The whole issue is very interesting. I have XP SP1 machines that don't seem to have this problem, even though XP SP1 is installed. I have to ask "what is it about SP1 that alledgedly broke things and what does adding the domain to the LDT supposedly fix things?" If the UDP packet is from the Exchange Server on the same network, and if the XP firewall thing isn't enabled, when what's the problem? The Firewall client doesn't handle LAT based connections, and doesn't handle incoming connections, unless they're part of an ongoing session with the Firewall service. So, which is so special about these Exchange new mail modification messages? I suppose its time for a packet sniff -- but how the LDT enters into the mix is quite odd, since the LDT is just used for determining how a name should be resolved.

Immediately upon installing XP SP1, my box exhibited the behavior- both with the FW client enabled and disabled. My domain was already in the LDT, and adding *.domain.com did not help. I followed the instructions a million times, and I could never get "new mail notification" to work- my only work around was a registry hack to make the Outlook client force a refresh every 30 seconds. Any insight?
