If the Cluster service is started simultaneously on both nodes, it may not start on one of the nodes and produce the following error message:

C:\>net start clussvc
The Cluster Service service is starting...............
The Cluster Service service could not be started.

A system error has occurred.
More help is available by typing NET HELPMSG 5086.

To determine what error message 5086 means, type net helpmsg 5086 at a command prompt. The result is:

The quorum disk could not be located by the cluster service.

The Cluster Diagnostic log indicates that arbitration did not succeed, with the following error message:


To determine what error message 170 means, type net helpmsg 170 at a command prompt. The result is:

The requested resource is in use.


When you start the service on both nodes at the same time, both try to arbitrate for the quorum device. Only one of the nodes survives the disk arbitration.

On the node that did not survive the arbitration, the cluster service mistakenly exits with a status of Stopped instead of Failed.

Service Control Manager's failure logic, as defined on the Recovery tab in a service's properties as viewed from the Services tool, is not activated by a Stopped status and the service is never restarted.


To work around this behavior, attempt to start the service again manually by typing net start clussvc at a command prompt.

To prevent this problem from occurring when the computers are restarted at the same time (for example, in the case of a power failure), stagger the timing of the Cluster service start. A delay of 30 seconds should be sufficient and should not have a significant impact on server up time. To do so:

  1. Right-click My Computer, and then click Properties.
  2. On the Advanced tab, click Startup and Recovery.
  3. Click to select the Display list of operating systems for nn seconds check box. Modify the time value to be 30 seconds different from the other node.


Microsoft has confirmed that this is a problem in Windows 2000 Advanced Server.


The following text is an excerpt from the Cluster log of one of the nodes reproducing this problem. The other node may not log these errors.
