From: CAMC1 on
I see a security error ever 10-20minutes in the event log of Exchange server
2003 Enterprs, SP2

Source: Security
Category Account Logon
Type: Failue Audit...
Event ID 680
User: NT Authority\System

logon account: (a mailbox e-mail account)
Source Workstation: DNAH-WORK
Error code: 0xC00000064

Mailbox logon account is valid, but there is no such computer on my LAN,
called DNAH-WORK

Is there a way to find out where this coming from?

Thanks
MC
