I am getting this massage in event viewer "The server was
unable to logon the Windows NT account 'asdfghjk' due to
the following error: Logon failure: unknown user name or
bad password. The data is the error code." The service
name is SMTPSVC
Can any one tell the reason
 
Hi,

Do you have SMTP service on this server? Is it running? Do you need it to
run? Is this Exchange server?

It looks to me that someone is trying to authenticate (is guessing usernames
and password) to SMTP service. If they figure out a valid account they will
be able to relay e-mails (spam) using your server.

Someone is trying to use the SMTP service to send mail and trying to
use the center row of keys as a user name. Could be a malicious
attempt, or could be a user is misconfigured for their email.
