Error The service did not start due to a logon failure. I agree with earlier statements that this is: 1. I'd prefer the virtual account just worked. Go to the "Log On" tab, clear out the password and click "Apply". Then I was able to start the service, with no problems. Office Office Exchange Server. Not an IT pro?

Remember that it can only be assigned to 1 computer at a time. To assign the user, first open up the Windows Services snap-in services. Find your service and edit the properties. As with any Windows user account, you must assign necessary permissions to disk.
Usually the service itself needs at least read permissions, and if the service needs access to anything else on disk or in the registry, you must grant the new account the appropriate permissions. I wanted to confirm what access is needed across the network. Since this account can only be assigned to a single computer, I wanted to make sure that network resources saw the network call as coming from this account and not from the computer account.
The reason I was worried about that is because all of the documentation I could find mentioned that the Virtual Accounts run as the Computer Account. This allowed me to point to a local path or a network path and ensure that the permissions worked as I expected. This test erased my concerns and confirmed that network access is made using this account. The 2nd type of service account is the Virtual Account. For example. The registry also maintains a mapping of instance ID to instance name.
Instance ID to instance name mapping is maintained as follows:. During setup, SQL Server Setup requires at least one user account to be named as a member of the sysadmin fixed server role. The sa account is always present as a Database Engine login and is a member of the sysadmin fixed server role. When the Database Engine is installed using only Windows Authentication that is when SQL Server Authentication isn't enabled , the sa login is still present but is disabled and the password is complex and random.
For information about enabling the sa account, see Change Server Authentication Mode. The per-service SID login is a member of the sysadmin fixed server role.
The account specified during setup is provisioned as a member of the RSExecRole database role. SSAS service account requirements vary depending on how you deploy the server.
Domain accounts are required to support the managed account facility that is built into SharePoint. For all other standalone SSAS installations, you can provision the service to run under a domain account, built-in system account, managed account, or virtual account.
For clustered installations, you must specify a domain account or a built-in system account. Neither managed accounts nor virtual accounts are supported for SSAS failover clusters. Administrator privileges are provisioned in the Analysis Services Server role. SQL Server During upgrade of SQL Server 9. If the service must interact with network services, access domain resources like file shares or if it uses linked server connections to other computers running SQL Server, you might use a minimally-privileged domain account.
Many server-to-server activities can be performed only with a domain user account. This account should be pre-created by domain administration in your environment. If you configure the SQL Server to use a domain account, you can isolate the privileges for the Service, but must manually manage passwords or create a custom solution for managing these passwords.
Many server applications use this strategy to enhance security, but this strategy requires additional administration and complexity. In these deployments, service administrators spend a considerable amount of time on maintenance tasks such as managing service passwords and service principal names SPNs , which are required for Kerberos authentication.
In addition, these maintenance tasks can disrupt service. If the computer isn't part of a domain, a local user account without Windows administrator permissions is recommended. The Local Service account is a built-in account that has the same level of access to resources and objects as members of the Users group. This limited access helps safeguard the system if individual services or processes are compromised.
Services that run as the Local Service account access network resources as a null session without credentials. Local Service isn't supported as the account running those services because it is a shared service and any other services running under local service would have system administrator access to SQL Server. The Network Service account is a built-in account that has more access to resources and objects than members of the Users group. Local System is a very high-privileged built-in account.
It has extensive privileges on the local system and acts as the computer on the network. For more information about supported encryption types, see Changes in Kerberos Authentication. Group-managed service accounts are not applicable in Windows operating systems prior to Windows Server Virtual accounts were introduced in Windows Server R2 and Windows 7, and are managed local accounts that provide the following features to simplify service administration:. No password management is required.
For information about how to configure and use virtual service accounts, see Service Accounts Step-by-Step Guide. Virtual accounts apply to the Windows operating systems that are designated in the Applies To list at the beginning of this topic. The following table provides links to other resources that are related to standalone managed service accounts, group-managed service accounts, and virtual accounts.
