RE: missing UDP packets?
Forget Send/Receive; it doesn't do anything in MAPI. Your router, proxy, or something like that is blocking the UDP packets. ©2000 Ed Crowley MCSE+Internet MVP kcCC+I® Protecting the world from PSTs and Bricked Backups! -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John Q Sent: Friday, December 21, 2001 9:42 AM To: Exchange Discussions Subject: Re: missing UDP packets?

missing UDP packets?
Recently, the client machines at my WAN sites stopped receiving new mail notifications. I have a sniffer on my exchange box and conducted two packet captures. The first is between exchange and a local machine. Outlook is open when the capture is started, and a new piece of mail is sent to the clients mailbox. The first two packets seen are UDP and sent from Exchange to the client machine, notifying it of the new mail. The second capture is between Exchange and a client on the WAN. Following the same procedure, it appears that no UDP packets are sent to that client machine. Any ideas why the Exchange machine is not sending these packets out? We are using Exchange 5.5 with Outlook 2000. The sites are connected via frame relay. There is no NAT taking place and the routers have no filters set on them.
