SCOM 2012R2 Alert notifications error - Failure to send, happens pretty frequently

Question

Afternoon,

I am seeing this fairly often in my production environment. The target machine referenced is the primary management server that is in the notifications pool. Both of the management servers are in the notifications pool. I was going to temporarily remove the primary management server from the pool but I do not know what effect that would have on the system? Why would the error reference the primary management server as the issue?

Failed to send notification using device/server 'servername' over 'Smtp' protocol to 'me@mydomain.com'.

Exception 'Microsoft.EnterpriseManagement.HealthService.Modules.Notification.SmtpNotificationException': Failure sending mail. --> Unable to connect to the remote server --> No connection could be made because the target machine actively refused it xx.xxx.xx.xx:25. Smtp status code 'GeneralFailure'

Thanks,
TS

Answer 1

Does the exchange server allow anon relay? I have used Exchange in the past, in labs, and you need a run as account, as exchange usually requires authentication.

Answer 2

Afternoon,

Nope, not this one, it requires authentication. There is another one I use as a backup/alternative, it allows anonymous. I get quite a few failures from it only because it is a bad setup/hardware and overloaded.

@Tony Strother

Hi,

For the e-mail notification, operations manager works just as a mail agent, for example, outlook/thunderbird. If the error message is the mail server refused the connection, it it suggested to look into the mail server logs (during the time period that error happens) to see if there is any clue.

Hope the above information helps.
