Applications Services dependency on Windows 2008 R2 RRS feed

  • Question

  • Hello All,

    We are running into issues on installation of a 32 bit application on windows 2008 R2 OS. The problem is the services of the application are interdependent and this can be seen in Windows Services panel but on Windows 2008 R2 there is no dependency between the services. Is there any specific change on windows 2008 R2 (64 bit) that may cause services dependency.

    Thanks in advance

    Thanks for the post here.

     

    In Windows XP®, Windows Server® 2003, and earlier versions of the Windows® operating system, all services run in the same session as the first user who logs on to the console. This session is called Session 0. Running services and user applications together in Session 0 poses a security risk because services run at elevated privilege and therefore are targets for malicious agents that are looking for a means to elevate their own privilege levels.

    The Windows Vista®, Windows Server® 2008 and Windows® 7 operating systems mitigate this security risk by isolating services in Session 0 and making Session 0 non-interactive. In Windows Vista, Windows Server 2008 and Windows 7, only system processes and services run in Session 0. The first user logs on to Session 1, and subsequent users log on to subsequent sessions. This approach means that services never run in the same session as users' applications and are therefore protected from attacks that originate in application code.
