Question

Service execution error in Windows Server 2008

Answer 1

Execution of a service in Windows Server failed

To begin we must check the Dependency Services . Sometimes a service may not start due to a problem with a dependency. The Services can sometimes form a hierarchical architecture in which the other services must be running for a service to start. It is more than clear that not all services have dependencies associated with them, but dependency services are quite common that certainly deserve a look if we are having problems to start a service.

With older operating systems, it was very difficult to track down problems with dependency services, but most of the newer versions of Windows Server become much easier.

To check the service dependencies, we must go to the "Service Control Manager" , Then we click on the " service" that we are having problems to start. Then we select the option " Properties" in the context menu that highlights. Once this is done, Windows 2008 Server will display a sheet of service properties.

In this property sheet, it contains a Dependencies tab. The Dependencies tab is divided into two sections:

• The upper part shows the services that must be running so that the service that we have selected to start.
• The bottom part of the tab lists the services that can not be started until the selected service runs.

We will take as an example in this case the Windows Firewall service can not be started unless the basic filter engine and the Windows Firewall Authorization driver have started. You can also see that there are no services that depend directly on the Windows Firewall services.

Something that is important to consider when solving service dependencies is that sometimes the dependencies can form a hierarchy of several levels. For example in the image above, you will notice that there is a plus sign to the left of the list for the Base filtering engine service and the Windows Firewall Authorization Controller service. If you click on these icons below, Windows will display a list of other dependencies that exist within the service hierarchy. As you can see in the following image, there are several dependencies for the Base Filtering Engine service, but no additional dependencies for the Windows Firewall Authorization driver service.

With this we should be able to check when a Service does not start because of some dependency, it is very useful when a Service does not want to run, and with this it is a good start to know where to start.
