I'm using MS 2003 For Exchange. We've got 2,3 admin for Exchange. Suddenly Mail Server is stop working. If you already configure in Outlook, outgoing is working but incoming is not. And Web mail is not working. when we check in services, all the services are working as usual. No Firewall. All admins said no configuration, not touching.

I would check external DNS connectivity and your MX record. CHeck this link here: http://www.mxtoolbox.com/SuperTool.aspxSee if you are able to resolve your info from outside of your netowrk. It sounds like something is messed with your MX or A Records.If that isn't the case look at the local server, anything in the queue? Also, check for any AV software that may have been updated or installed.Overview of Exchange Server 2003 and antivirus softwarehttp://support.microsoft.com/default.aspx/kb/823166SF - MCITP:EMA, MCTS: MOSS 2007, OCS 2007, Exchange 2007

You need to run certain commands in order to bring database up. From Bin folder run eseutil/mh <path of database> check for log file required and make sure logs are available in logs folder and then run Eseutil /r to replay logs.
