    Hello,

    I just got done updating half of my OCS infrastructure which was to include the steps here: http://support.microsoft.com/kb/968802 and then shortly after I would run a windows update and update the rest of the server.

    Well, after some users rebooted their local machine, they are unable to connect to OCS with an error of a pool is down. What's interesting is that it's not the actual pool that they are in, just a pool in the environment. (the actual error was not recorded on the user end)

    When I go into the machine and others that I've updated, the Front End service has "Start Pending" as a status with everything else running. Everytime I try to start the service I don't get an error but when I go into the event log, I get the following error:

    The process IMMcuSvc(4660) failed to send health notifications to the MCU factory at https://server.domain.net:444/LiveServer/MCUFactory/.
    Failure occurrences: 13, since 2/24/2011 2:39:39 PM.

     

    I browsed around and then exported and reimported the certificate thinking that that would fix the problem. Now I have this error:

    Log Name:      Office Communications Server
    Source:        OCS Protocol Stack
    Date:          2/24/2011 3:25:01 PM
    Event ID:      14361
    Task Category: (1001)
    Level:         Error
    Keywords:      Classic
    User:          N/A
    Computer:      server.domain.net
    Description:
    Unable to use a certificate as configured

    Transport:TLS, IP address:*, Port:5061. Error:0x0xC3E93C0D (SIP_E_STACK_TRANSPORT_CERT_NOT_FOUND).
    Cause: The certificate may have been deleted or the configuration is erroneous.
    Resolution:
    Ensure that a valid certificate is present in the local computer certificate store. Also ensure that the server has sufficient privileges to access the store.

    Now, I know I probably imported the cert wrong so I'm going to work on that but before I keep going down this path, is it a certificate problem?
