Gateway Server in SCOM

Hi experts,
I need your advice on the below point
* It is recommended to keep Management server in the same datacenter. But in case if we got another datacenter with less network bandwidth, can we place GATEWAY server there though its a trusted zone. Please clarify.
Regards, Pratap

Hello Pratap,
If you need a gateway server, then it has to be in the another DataCenter and the agents in that same datacenter will point to the Gateway Server. The best part about this will be you do not need to install certificates on each server in that second data
center. All you need to do is configure certificates on the Gateway Server and the Management Server, where the Gateway Server will be pointing to.
And Since Bandwidth is an issue, if the agents from different datacenter point to the MS (in another DC) directly, then it will take up a lot of bandwidth for each agent however, if the communication is only between the Gateway Server and MS then that should
utilize less bandwidth.
Hope this helps!

  • SCOM Gateway Server Issue

    Hi All
    I am having an issue related with my LAB Gateway server with SCOM 2012 SP1
    I am having 2 Management server and 3 gateway server in my LAB. Now I am trying to install a new Gateway server. But its not showing in Management server list. Its showing as a SCOM Client. have any one faced this issue or any idea.
    Your earlier response is appreciated.

    Hi,
    Whether the gateway server is listed under pending management, if it is, try to remove it from here before running the approval.
    Please also go through the below similar thread for more details:
    SCOM 2012 R2 Gateway installation error and no System Center Management server after install
    http://social.technet.microsoft.com/Forums/en-US/ce6d0a73-c31d-4c26-85d4-d3cce35d48c3/scom-2012-r2-gateway-installation-error-and-no-system-center-management-server-after-install?forum=operationsmanagerdeployment
    Please follow the below steps:
    1) Validate that the gateway server can ping the Management Server that it will need to communicate with and can telnet to port 5723. Also validate that the OpsMgr Management Server can ping the Gateway server. If traffic doesn’t route between these systems,
    or they cannot resolve each others names, or they cannot communicate on port 5723 the Gateway will not function.
    2) Install the gateway server from the OpsMgr media (Gateway management server).
    When installing, choose the Management Server that we have determined will be the primary Management Server for gateway servers in the environment and configure the gateway to run as local system.
    3) Next if required in the OpsMgr console we delete the agent from pending management if it appears in that view.
    4) Perform the approval of the gateway by transferring the Microsoft.EnterpriseManagement.GatewayApprovalTool.exe from the installation media to the appropriate path to run it from (c:\program files\System Center Operations Manager 2012\Server is the default
    location)

    2. Import those certificates into the target computers by using the MOMCertImport.exe tool.
    3. Distribute the Microsoft.EnterpriseManagement.GatewayApprovalTool.exe to the management server.
    4. Run the Microsoft.EnterpriseManagement.GatewayApprovalTool.exe tool to initiate communication between the management server and the gateway
    5. Install the gateway server.

  • Gateway server and Management server in SCOM 2012

    What are the main Different between Gateway server and Management server in SCOM 2012?
    I have referred this , is there anything ?
    http://blogs.technet.com/b/momteam/archive/2008/02/19/10-reasons-to-use-a-gateway-server.aspx

    1) Management server can write data , gathered from agent, directly into operations manager database. Gateway server should forward data, collected from managed agent to management server.
    2) In a unturst environment for example workgroup or untrust domain, and you do not want to deploy a certificate to every monitored agent, you should deploy gateway server rather than managment server.

  • SCOM Agents in DMZ via Gateway Server

    I need to monitor all the web servers in our DMZ by placing a Gateway Server between them and SCOM RMS.
    Jus a  simple Question I have ................do I need to install certificates on all my web servers in DMZ to talk to SCOM Gateway Server or not????
    If I need certificates on all my DMZ webservers then what is the purpose of a gateway server?
    thanx

    Hi There,
    The certificate installation depends on the scenario.
    Scenario 1# If the Gateway server is in domain but, the servers in DMZ are not part of domain. We need certificate for each server to create Trust with Gateway server. Otherwise Gateway may not authenticate agent servers due to domain mismatch. And AD authentication
    is must while installing Agents.
    Scenario 2# If the Gateway Server and Agent Servers are in same domain in DMZ. In this scenario we need to have certificate only for Agent Servers not for Agent Servers, as the agents will be authenticated using AD (due to same domain).
    Scenario 3# If none of the Gateway server or Agent Server are in Domain. This case we need to issue certificate for each Server, including Gateway Server. This scenario the Gateway server will work as a mediator for communication only(in a Manner of speaking).
    Be sure that Gateway server concept can be avoided with servers DMZ and not in domain, but this will increase the security risk by authorizing multiple endpoint rules in firewall.
    Below link will give you more info about Gateway servers and its uses.

  • SNMP Monitoring behind SCOM Gateway Server

    Hi All
    Is it possible to monitor Network devices / SNMP that sit behind a SCOM Gateway server? If so, how do these get discovered?
    I have a need to monitor devices like HP printers, WAP, JetDirect cards, EPOS equipment etc. on a site that doesn't have SCOM on-premise.
    Are there any limitations to this?
    Thanks

    Hi,
    Yes, it is possible. when you create discovery, you may specify that it should run from gateway server.
    On the device you want to monitor, set your SNMP public community string to point to the IP address of the SCOM Gateway server. In the SCOM Administration console, choose Network Devices in the Discovery Managment Wizard choose network device and click next.
    In the next screen enter the IP address of the network device you want to monitor and under the mangment server drop down choose the gateway server who’s IP you entered in the SNMP string earlier.
    Here is a similar thread for you reference:

    In addition, you may check is there any management pack for your devices and import them into your management group.

  • Gateway server not able to authenticate

    Hello SCOMMers :)
    I have a issue with my SCOM 2012 R2 system that i just can't get my head around.
    We just purchased a brand new SCOM server that I have migrated our environment to, moved the databases, reporting server and finally i got things up and running after some issues with the DB move.
    So i now have 2 SCOM management servers in my environment and four gateway servers, the gateway servers are communicating to the old SCOM server and i want to move them over to the new SCOM server. 
    I ran the powershell commands from this technet article and thought everything was under
    control. But none of the GW servers started communicating with the new SCOM server. 
    I have of course checked the certificates, hosts file, DNS and firewalls, and i reran the MOMCertImport.exe utility. Also checked that the certificate serial number was correctly inserted to the registry after the MOMCertImport.exe was run. (HKLM\Software\Microsoft\Microsoft
    OperationsManager\3.0\Machine Settings, binary value named ChannelCertificateSerialNumber contains the serial number of the certificate in a reverse order)
    Still i was unable to get the GW server to communicate to the correct management server so i decided i to reinstall the GW server so I could set the name of the new SCOM management server during the GW setup. Before i did the reinstall i ran the Microsoft.EnterpriseManagement.GatewayApprovalTool.exe
    with the /Delete parameter, the command ran successfully.
    When i do the install i still cannot get the communication up and running, the GW server gives me the following errors in the eventlog.
    The GW server appears in my Management Servers list but stays in the Not monitored state.
    Event ID: 20057
    Failed to initialize security context for target MSOMHSvc/<ServerFQDN> The error returned is 0x80090303(The specified target is unknown or unreachable). This error can apply to either the Kerberos or the SChannel package.
    Event ID: 20071
    The OpsMgr Connector connected to tmg-app92.mg.local, 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.
    Event ID: 21001
    The OpsMgr Connector could not connect to MSOMHSvc/<ServerFQDN> because mutual authentication failed. Verify the SPN is properly registered on the server and that, if the server is in a separate domain, there is a full-trust relationship between the two domains.
    Event ID: 21016
    OpsMgr was unable to set up a communications channel to <ServerFQDN> and there are no failover hosts. Communication will resume when <ServerFQDN> is available and communication from this computer is allowed.
    I have installed new certificated on both GW and management server, and i did the SCOM GW installation multiple times, but the issue is the same and the eventlog error also are the same.
    Does anyone have any clue to what might be wrong?
    Thanks!

    Hi,
    After you deleting the gateway with Microsoft.EnterpriseManagement.GatewayApprovalTool.exe, the gateway object is only marked as deleted in databases. Therefore, try to use different name for the new installed gateway, so the old parameters will not
    be associated with the new gateway.
    For the communication\certificates problems check these links:

  • Error while running gateway approval tool (SCOM 2012)

    We get an error saying "The gateway server does not exist: <GW server name>" while running gateway approval tool in SCOM 2012 MS. referred several blogs, but no help. MS servers are in healthy state and Ops DB has enough free space.
    Port 5723 is the only port open between GW and SCOM MS servers. Could anyone assist with a solution pls?

    Did you first install SCOM gateway server role on that GW Server. are the certificates installed properly.
    Also please confirm that the GW server name exists in AD too.
    Please check that GW server does not already exists in SCOM as a computer object. Check the SCOM database too for any stale entry of the GW Server.
    Once the above are clear. Then you can run the gateway approval tool with action =delete.
    After that again try to run the gateway approval tool with action =create.
    Hope this helps.
    Thanks, S K Agrawal

  • Gateway server in non trusted domain

    I have been trying to monitor a non trusted domain from SCOM 2012 R2. All servers are running Server 2012 R2 and this is running in a home lab.
    I have added the trusted root certificate to both the gateway server and the SCOM management server. 
    SCOM Management Server is OM01.Corp.ViaMonstra.Com.
    Gateway Server is BMC-DC01.BMC.Intern.
    Both of these servers have the trusted root cert for ViaMonstraRootCA.
    I then created a OpsMgr certificate by copying the ipsec(offline request) and making a new template. This has server and client authentication.
    I requested this on both the gateway server and the management server and exported it from the user store and into the local computer store (with the private key). 
    I also ran MOMCERTIMPORT on both servers, only one cert showed up on each server which was the one I created and imported into the personal area of the local computer store.
    I have checked that the FQDN name of the management server appears in the required opsmanager registry keys and also the required tls2.1 keys are in place.
    I have also run the gateway approval tool which can with success and installed the gateway server role using the opsmgr install media.
    I see the event 20053 stating the opsmgr connector has loaded the specified authentication certificate succesfully.
    Yet I will get the events 20057,21001,20071,21016
