SMTPSVC Event ID 402 Error
Posted on 2008-10-28
I have a client running Exchange 2003 SP2 on a Windows 2003 server. Everything had been working fine for the last few years, but over the last couple of months the server stops processing incoming email, the maximum number of connections in Exchange is reached and it starts logging the SMTPSVC 402 errors. No email is delivered until the server is restarted. The users can still send outgoing email, but not receive incoming. I need help figuring out what may be causing the Exchange server to stop processing the email, thus leading to the connections filling up and creating the SMTPSVC 402 error. I have checked on mxtoolbox.com and the server is not a relay.
