Hello, I have a problem with my SCOM 2012 SP1. When it tries to send notification by IM Channel I get the following alert in SCOM:
Notification subsystem failed to send notification using
device/server 'live.august.ru:5060' over 'sip' protocol to
'sip:user@august.ru'.
Microsoft.Rtc.Signaling.OperationFailureException: The GetInbandDataAsyncResult
operation has failed with message: "The data session subscription to server
failed.". See the InnerException and FailureReason properties as well as the
logs for additional information. . Rule id:
Subscription077dc311_59c0_4ba5_a432_072b486cd287
At the same time the following event in the Application Event Log generates on the server with IM service:
Event Type: Warning
Event Source: Live Communications Server Authentication
Event Category: (1003)
Event ID: 16435
User: N/A
Computer: LCS
Description:
At least one invalid authentication signature was detected.
There were 2 messages with invalid signatures in the last 7112 minutes. The last one had the FROM header: sip:OpMngAdmin@august.ru.
Cause: This could be due to a client or server which is not handling authentication correctly, or it could be due to an attacker.
Resolution:
None needed unless the failure count is high (>100). Check your network for any rogue clients. Restart the server if problem persists.
Notifications sent by the SMTP channel work fine!
I Have the following Servers:
LCS (live.august.ru) - Win 2003 EE SP2 + Live Communication Server 2005 SP1
SCOM - Win 2012 + SCOM 2012 SP1
Also I have a third server (Win 2003 + SCOM 2007 R2) and it sends notifications to the same VMLCS server successfully. The configurations of IM Channels are identical on both servers:
IM server: live.august.ru
Return address: sip:OpMngAdmin@august.ru
Protocol option: TCP
Authentication method: Kerberos
IM port: 5060
I tried to change the Authentication method to NTLM, and the port to 5061, but it doesn't help...
