One cluster node failed.


Recently i have occured a problem when starting the SAP System in cluster. It reported the error:


The SAP<SID>_00 service was unable to log on as cowealth\SAPService<SID> with the currently configured password due to the following error:

Logon failure: the user has not been granted the requested logon type at this computer.

Service: SAP<SID>_00

Domain and account: <domain name>\SAPService<SID>.

This service account does not have the necessary user right "Log on as a service."

User Action

Assign "Log on as a service" to the service account on this computer. You can use Local Security Settings (Secpol.msc) to do this. If this computer is a node in a cluster, check that this user right is assigned to the Cluster service account on all nodes in the cluster.

If you have already assigned this user right to the service account, and the user right appears to be removed, a Group Policy object associated with this node might be removing the right. Check with your domain administrator to find out if this is happening.

For more information, see Help and Support Center at

So one node started,and one node failed in cluster. I guess the account <domain name>\SAPService<SID> got something wrong, does anyone could tell me which group should this account belong to?

Thanks and Best Regards,
