You cannot access VMM management server RRS feed

  • Question

  • I installed Rollup 1 (via Windows Update). No errors were logged. Now when I open App Controller (which had been configured for single sign on) I'm prompted for credentials. When entered I'm presented with the following error:

    Category: Critical
    Description: You cannot access VMM management server <redacted>.
    Details: Category: Critical
    Message: System.ServiceModel.Security.SecurityNegotiationException
    Description: The remote server did not satisfy the mutual authentication requirement. 

    I reapplied the single sign on settings (they were still present) but no change. Any ideas?

  • Hi William,

    When configured for single sign-on you shouldn't be prompted for credentials.

    If App Controller is not configured for single sign-on are you able to connect to the VMM management server?

    Thanks

  • No. I removed the single sign-on configuration, rebooted the server and logged in with credentials for an administrator. Same error. Basically App Controller is dead.

  • Hi William,

    To help narrow down the issue:

    1. Is your VMM management server clustered?
    2. Is App Controller running as a service account or a domain account?
    3. Are the App Controller server and the VMM server in the same domain?
      If there are different domains:
      1. Is there a 2 way trust between the domains (forest/domain)?
      2. Is the user account connecting to App Controller in the same domain as the App Controller server?

    Thanks

  • VMM management server is not clustered

    App Controller is running under a domain account

    VMM and App Controller are in the same domain (right now on the same server)

  • Hi William,

    If the SPN for the VMM server is not be registered correctly it will cause mutual authentication to fail.

    An easy way to check if this is the issue is to run the Virtual Machine Manager Configuration Analyzer (VMMCA).

    This will identify if there is a configuration issue with VMM that may be causing the issue.

    Thanks

  • Thanks for the response. I wound up reinstalling VMM to clear this, installed the rollup and didn't see the problem again. Can't say what the issue was but at least it's behind me.
