Hello everyone,
I've found browsed tons of guides and figured I would reach out here now.
Background:
I have a gateway server (GW) in a DMZ zone which communicates with my Management server (MS). From what I can tell the GW server communicates successful with the MS, since I find similar events in the eventlog (I'll upload picutres when my account is verified):
'New configuration became active. Management group...'
There is a warning in the Operations manager console, but they are from the installation and does not appear to go away - even though I've changed the default action account & re-installed the agent on the GW server. ¯\_(ツ)_/¯
"The Health Service could not log on the RunAs account 'domain\ServerActionAccount' for management group Groupname. The error is The user name or password is incorrect.(1326L). This will prevent the health service from monitoring or performing actions
using this RunAs account"
But, the real problem is that my first (of many) DMZ client server (Lets call the client 'DMZserver') can't communicate with the GW. I was a little confused during the MOMCertImport.exe stage if I should import the GW certificate or create one for the server
itself, so I tried both options - without any luck.
In the eventlog from the DMZServer I can see the follow errors (20071 & 21016).
'The OpsMgr Connector connected to GW, but the connection was closed immediately without authentication taking place. The most likely cause of this error is a failure to authenticate either this agent or the server . Check the event log on the
server and on the agent for events which indicate a failure to authenticate.'
&
'OpsMgr was unable to set up a communications channel to GW and there are no failover hosts. Communication will resume when GW is available and communication from this computer is allowed.'
I have checked:
- Telnet 5723 between DMZserver & GW
- Telnet 5723 between GW & MS (Please note that I have
not configured the '/ManagementServerInitiatesConnection=True'-parameter
during the 'Microsoft.EnterpriseManagement.gatewayApprovalTool.exe'-phase from the MS server.)
- I have also confirmed that 'HKLM\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Machine Settings\ChannelCertificateSerialNumber' value of the certificate is matching the thumbprint.
- There is DNS resolution between DMZServer & GW.
- There is DNS resolution between GW & MS
- There is nothing under Administration-> pending management' in the Operation Console.
- I have imported the Root & Intermediate certificates on all 3 servers.
I am clearly missing something, but I've looked in to a few guides and none of those I've looked at have any additional steps.
Anyone have any tips?
best regards,
TB
