Exchange 5.5 SP2 NT 4.0 SP6a We have an X.400 connector setup over dial-up with one of our vendors and they are telling us that over the last 2 weeks they have been experiencing a problem where the connection seems to be terminating abnormally and the messages are transferred to our system, but backing up on their system, because they are not receiving a confirmation that the messages have been transferred. I have found a number of articles that seem very similar. The one that most closely describes our situation is Q193380. But the only Event ID associated with this on our Exchange server is 9215. The relevant KB articles referencing 9215 are: Q170056 Q154301 Q164400 Q182619 Q261251 But none seem to really pertain to this situation. I am considering going to SP4, but I found mention of a similar error that only manifests itself with SP3 or 4. So I am a little leery of doing this on a production server. Has anyone come across this before? TIA Chris Bodnar The Lehigh Group 610-966-9702 X:134 http://www.sunbelt-software.com/ntsysadmin_list_charter.htm
