Management point - service unavailable

    Question

  • Hello all, I have a clearly new issue with a secondary site management point whereby MP role is installed succesfully, no major errors are logged in the MPMSI.log and yet, service is unavailable - result, clients cannot get policies from secondary site MP

    MPCONTROL.LOG shows the following errors:
    Call to HttpSendRequestSync failed for port 80 with status code 503, text: Service Unavailable SMS_MP_CONTROL_MANAGER 9/4/2009 10:19:04 AM 4360 (0x1108)
    Http test request failed, status code is 503, 'Service Unavailable'. SMS_MP_CONTROL_MANAGER 9/4/2009 10:19:04 AM 4360 (0x1108)
    Successfully performed Management Point availability check against local computer. SMS_MP_CONTROL_MANAGER 9/4/2009 10:19:04 AM 4360 (0x1108)

    The most recent IIS log file(s) show similar and apart entries with errors 401, 404, and 501:

    CLIENT LOG

    CCMExec.log entry

    [CCMHTTP] HTTP ERROR: URL=http://SITESERVER.FQDN/ccm_system/request, Port=80, Protocol=http, SSLOptions=0, Code=0, Text=CCM_E_BAD_HTTP_STATUS_CODE CcmExec 9/4/2009 11:13:51 AM 4176 (0x1050)

    Additional observation:
    When launchin the local IIS Admin console, I noticed that the following objects under default website would display "Service Unavailable" when attempted to right click and select browse:

    1) SMSSMP
    2) CCM_Incoming (this virtual directory folder path should also list certificate files which are missing)
    3) CCM_Outgoing
    4) CCM_System
    5) SMS_MP

    Please note that the MP_GetAuth.log and MP_GetPolicy.log files have not yet been created among other MP_*.logs.

    Your input would be much appreciated.

  • Hello Torsten,

    I removed the secondary site.  Removed and reinstalled IIS.  Reinstalled secondary site and enabled the MP role. Same issue. Reading the event logs, there was error ID 1009 indicating the app pools were stopped due to previous errors:
     
    Event Type: Warning
    Event Source: W3SVC
    Event Category: None
    Event ID: 1009
    Date:  9/8/2009
    Time:  4:19:12 PM
    User:  N/A
    Computer: SITESERVER
    Description:
    A process serving application pool 'SMS Management Point Pool' terminated unexpectedly. The process id was '4324'. The process exit code was '0xffffffff'.

    Doing a web search, I found the following article http://blogs.iis.net/brian-murphy-booth/archive/2007/03/22/how-to-troubleshoot-an-iis-event-id-1009-error.aspx which indicates that error outlined above could be due to access and or permissions.

    After trying a few things as suggested in the blog listed above, the issue was being caused by name resolution.  My colleague made an adjustment so the site server could be accessed using a short name resolution.  It seemed this fixed the issue.

    Thank you Torsten for your help.  And thank you Microsoft for these very valuable forums that help me ease my Admin job.

  • Have you tried uninstalling the MP, uninstalling IIS, rebooting and reinstalling everything again?

  • No.  I will remove and reinstall IIS and let you know the end result.  I believe I do not need to remove the entire product just to create the MP.

  • Although not exactly caused by a DEFECTIVE or failing to install Management point, a similar problem as recorded in this thread started to reappear:  Secondary site clients failing to distribute software.

    CCMExec.log for clients in secondary sites --which reports to proxy MPs-- started to log similar error: 

    [CCMHTTP] HTTP ERROR: URL=
    http://SITESERVER/ccm_system/request, Port=80, Protocol=http, SSLOptions=0, Code=0, Text=CCM_E_BAD_HTTP_STATUS_CODE             CcmExec              2/1/2010 6:10:21 PM       1624 (0x0658)

    ExecMgr.log entry:

    Execution Request for package SIG000DF program McAfee Superdat state change from WaitingContent to WaitingContent execmgr 2/1/2010 4:56:10 PM 1028 (0x0404)

    =======================================
    Resolution:
    As discovered, the clients were confused as they were trying to access non existing management or distribution points as instructed by AD.

    The
    http://SITESERVER  Management Point seen by the clients no longer exists.  Somehow, the AD containers for those old site servers (MPs) reappeared under the AD Systems ->Systems Management container -> SMS-MP-SITECODE-SITESERVER.

    The actual solution for this issue was to delete those "old" MP containers from AD.
