My Exchange server 2000 has been running fine for 8 months. I have the latest updates and patches. It is running on Advanced Server 2k. Recently SMTP incoming mail stopped. All my clients can send out going mail with no problems. Incoming mail comesin with no errors. Log files show no errors. The information store shows mail in it but does not pass mail to the users mailboxes. Going in the information store I find the queues shows the mail being passed to the catagorizer but the catagorizer does not pass it on, nor does it show it is receiving mail. I could not find a hot fix so I brought up another Exch. server but need to get that mail to the new one.What happened?
