Yes, individual sites connected to internet with ADSL and public addresses, then the sonicwalls create the VPN using the addresses at each site
I may have to revise my setup, but I assumed even if it wasn't ideal, error messages would be generated for failed deliveries Thanks Nik -----Original Message----- From: Ed Crowley [mailto:[EMAIL PROTECTED]] Sent: 17 January 2002 03:04 To: Exchange Discussions Subject: RE: Message disappeared during link outage If by VPN you mean over the Internet, that topology probably calls for separate sites connected by X.400 connectors.

Each office has an Exchange Server 5.5 SP3 on NT Server 4 SP6a, with 1 of them having an IMC. There is one Organisation/Site with multiple servers to represent the different offices, and all staff at each office have their mailboxes on their local servers. It was reported to me that a Director (isnt it always?) sent an email to the Managing Director (arrrgh!) within the same organisation, but whose mailbox was located on another server, seperated by the ADSL VPN link. The mail never arrived, and no error was received by sender or recipient. Upon closer inspection, the following event is noted in the senders local NT server event log at the same time that they sent the message. Event ID - 9316 Source - MSExchangeMTA An RPC communications error occurred. No data was sent over the RPC connection. Locality table (LTAB) index: 238. Windows NT error: 9317. The MTA will attempt to recover the RPC connection. (BASE IL INCOMING RPC 40 522) (12) There were no errors immediately before or after this event (closest 5 hours) and I assume there was some problem with the ADSL link at that time, not uncommon, and also suggested by some errors on the main server (the 'hub' of the VPN). What I need to know is a) why wasn't the mail delivered when the link was restored and b) why was no non delivery error returned. Mail normally flows fine between all servers. I have followed the instructions in technet doc - http://support.microsoft.com/default.aspx?scid=kb;en-us;Q247782 but the "concurrent xapi sessions" was already at "50". Its not so important to ensure mail delivery, as it is to make sure we know when a message has not been delivered. Thanks in advance for any help Nik _________________________________________________________________ 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] _________________________________________________________________ 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]
