Connects the local server computer to a farm.

Connect-SPConfigurationDatabase [-DatabaseName] <String> [-Passphrase] <SecureString> -DatabaseServer <String> [-AssignmentCollection <SPAssignmentCollection>] [-DatabaseCredentials <PSCredential>]

The Connect-SPConfigurationDatabase cmdlet connects the current server to the specified configuration database.

Essentially, this cmdlet connects the server to the farm. If the current computer cannot be connected to a farm, the following error message is displayed:

"This machine is already connected to a SharePoint farm. See: Dismount-SPConfigurationDatabase"


Parameter Required Type Description




Specifies the name of the configuration database to which to connect the server.

The type must be a valid database name; for example, DB1.



A valid database server, such as "DS"

Specifies the server on which to create the configuration database. The default value is the local computer name.




Specifies the secure password phrase for connecting the current server to the configuration database.

The type must be a valid secure string; for example, MyBDCApp1serverkey.




Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.




Specifies the PSCredential object that contains the user name and password to be used for database SQL authentication. If this parameter is not specified, the current user is used.

The type must be a valid PSCredential object.


Connect-SPConfigurationDatabase -DatabaseServer "ServerName\InstanceName" -DatabaseName "SharePointConfigurationDatabaseName" -Passphrase (ConvertTo-SecureString "MyP@ssw0rd" -AsPlainText -Force 

Start-Service SPTimerv4

This example joins the local server computer to a farm that is configured to use the database SharePointConfigurationDatabase on an instance of SQL Server by using the name ServerName\InstanceName with the passphrase MyP@ssw0rd.
