Basically they don't update until a user clicks on a nether message or waits in excess of 20 minutes. Needless to say users are frustrated by this due to the fact that they don't "think" their mail has been sent. Is there a work arround for this? Client side notification of disabeling "new mail notifications"? The description of why this particular situation does not work is below, read into if you wish. -John Q Jr. Currently machines on the WAN network are using internal IP addresses (which are not routable via our network). When the machines send packets to our network, the WAN router converts the IP addresses into a public IP address (an address our router can actually reply to). The problem in hand is that when Exchange receives packets from the client, it looks into the payload information (information inside the packet, not the header) to figure out where it should be sent. Case in point: Workstation 10.10.2.15 is connected to x.230.24156/57. Due to NAT, the Exchange servers sees x.154.10.42 connected (it can communicate back fine). Once the user receives a piece of mail, the Exchange server replies to 10.10.2.15 (it had to have looked this information up from the payload data) and of course this IP is not routable. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
