SQL servers agent service failure

  • I am installing SQL server on cluster but SQL Agent has failed to comeonline with bellow errors in event log.

    Cluster event :

    This issue occurs because the Cluster service does not register the fully qualified domain names (FQDN) of a resource name to the Local Security Authority (LSA).

    The Cluster service registers the FQDN of a resource name to LSA and to the DNS database at the same time. However, the DNS registration occurs one time every 24 hours. Therefore, there is a delay in the registration of the FQDN to LSA.

    Due to this i am unnable to bring resouces online on NODE1

  • Try disabling UAC:

    Here is the complete process on how to proceed with this:

    Go to Command prompt and run the below command to disable the UAC

    Reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f

    Other way of doing the same is Go to Registry Editor

    Start --> Run -->Type RegEdit and hit Enter key

    In the Registry Editor, Navigate to the below folder

    HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

    Right click on system folder and place the mouse pointer on New --> click on "DWORD Value" (New Value will be created under System) -->Rename it as "EnableLUA" and default value will be 0 leave as it is.

    Then restart your computer. Now you will start getting nagging prompts to re-enable UAC, if needed you can disable these prompts. To avoid this click the bubble at the side, it should say “Change the way Security Center alerts me”, click that, and then click “Don’t notify me and don’t display the icon”.

    This should solve the issue.
