Thanks for your response.
I've unbound the sinks and unregistered the AV and the problem has not reoccurred. Of course - I don't want to run that way. GFI/Sunbelt wants me to turn on a crash dump debugger and wait for the system to crash. I hate to do that since I lose all incoming mail when it crashes and the senders aren't even getting notice that their message was not delivered. It may be my only option but I thought if I could rule out a corrupt IS first, then I might be able to avoid the pain of lost messages. See my previous reply - the only entry that is somewhat new is the calendar entry error (See my previous reply) Yes, deleted items retention is turned on and I can have him check that although, if the message just "disappeared" then I doubt it would be there. I would be inclined to blame it on user error but this guy is actually pretty good and things disappeared on him twice so that is why I'm questioning the integrity of my IS.

If you unbind do your problems go away? Don't forget to unbind the smtp and AV scanner. Do you have any IS store errors? Do you have Deleted Item Retention turned on? Go to his folder that the files were missing and see if you can do a Deleted Item Recovery on it. Greg Sweers CEO ACTS360.com <http://www.acts360.com/> P.O.

The antivirus engine had stopped and after that the event log registered thousands of entries that the Ninja VSAPI had refused Microsoft Exchange InfoStore request to scan a message because the Ninja Store Scanner is down. (I'm using Vipre E-mail Security for antivirus/antispam). No other unusual entries were found in the event log. I rebooted the server and it took a really long time to shut down. When it came back up the Ninja Store scanner service was not started but I was able to start it manually. Without going into a lot more detail I'll just say the info store wasn't working right. Subsequent attempts to stop the IS service failed. I disabled Vipre, rebooted again and everything resumed normal function (except no antivirus/antispam). I updated Vipre and reenabled its services. The following morning the server had crashed in the same way. When it crashes messages are not delivered to inboxes and the sender does not get an NDR. Since then I've had a user claim that he tried to move some messages from one folder to another and they disappeared. Later he told me that he had an important message in his inbox and when he tried to open it, it disappeared. So, the questions I have are 1) Could a corrupt info store cause the av scanner to fail like this? If so, how can I check for/repair the store? 2) Does this guy's claims seem possible that messages are just disappearing? Details Exchange Server 2003 with both front and backend servers.
