DESCRIPTION
The Test-DscConfiguration cmdlet tests whether the actual configuration on the nodes matches the desired configuration. Specify which computers for which you want to test configurations by using computer names or Common Information Model (CIM) sessions. If you do not specify a target computer, the cmdlet tests configuration of the local computer.
If the desired and actual configurations match, the cmdlet returns a value of $True. Otherwise, it returns a value of $False.
EXAMPLES
Example 1: Test configuration for the local computer
PS C:\> Test-DscConfiguration
This command tests configuration for the local computer.
Example 2: Test configuration for a specified computer
PS C:\> $Session = New-CimSession -ComputerName "Server01" -Credential ACCOUNTS\PattiFuller
PS C:\> Test-DscConfiguration -CimSession $Session
This example test configuration from a computer specified by a CIM session. The example creates a CIM session for a computer named Server01 for use with the cmdlet. Alternatively, create an array of CIM sessions to apply the cmdlet to multiple specified computers.
The first command creates a CIM session by using the New-CimSession cmdlet, and then stores the CimSession object in the $Session variable.
The command prompts you for a password.
For more information, type Get-Help New-CimSession.
The second command tests configuration for the computers identified by the CimSession objects stored in the $Session variable, in this case, the computer named Server01.
Example 3: Test configurations with detailed results
PS C:\> Test-DscConfiguration -ComputerName "Server01", "Server02", "Server03" -Detailed
This command tests configurations for a set of computers specified by the ComputerName parameter and returns detailed information that includes the overall state, resources that are in the desired state, resources that are not in the desired state and computer name.
Example 4: Test configurations specified in a folder
PS C:\> Test-DscConfiguration -Path "C:\Dsc\Configurations"
This command tests configurations that are defined in a folder specified by the Path parameter. The configurations are tested against a set of computers, each identified by the file name of the configuration file.
Example 5: Test configurations specified in a file
PS C:\> Test-DscConfiguration -ReferenceConfiguration "C:\Dsc\Configurations\WebServer.mof" -ComputerName "Server01", "Server02", "Server03"
This command tests a configuration defined in a file against a set of computers specified by the ComputerName parameter.
PARAMETERS
-AsJob
Indicates that this cmdlet runs the command as a background job.
If you specify the AsJob parameter, the command returns an object that represents the job, and then displays the command prompt. You can continue to work in the session until the job finishes. The job is created on the local computer and the results from remote computers are automatically returned to the local computer. To manage the job, use the Job cmdlets. To get the job results, use the Receive-Job cmdlet.
To use this parameter, the local and remote computers must be configured for remoting, and on Windows Vista and later versions of the Windows operating system, you must open Windows PowerShell with the Run as administrator option. For more information, see about_Remote_Requirementshttp://go.microsoft.com/fwlink/?LinkId=623526 (http://go.microsoft.com/fwlink/?LinkId=623526).
For more information about Windows PowerShell background jobs, see about_Jobshttp://go.microsoft.com/fwlink/?LinkID=113251 (http://go.microsoft.com/fwlink/?LinkID=113251) and about_Remote_Jobshttp://go.microsoft.com/fwlink/?LinkID=135184 (http://go.microsoft.com/fwlink/?LinkID=135184).
Type: SwitchParameter
Parameter Sets: (All)
Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.
Type: CimSession[]
Parameter Sets: CimSessionAndPathSet, CimSessionAndReferenceConfigurationSet, CimSessionSet
Aliases:
Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False
-ComputerName
Specifies an array of computer names on which this cmdlet tests the configuration. The cmdlet tests the configuration document in the location specified by the Path parameter to these computers.
Type: String[]
Parameter Sets: ComputerNameSet, ComputerNameAndPathSet, ComputerNameAndReferenceConfigurationSet
Aliases: CN, ServerName
Required: False
Position: 1
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False
-Credential
Specifies a user name and password, as a PSCredential object, for the target computer.
To obtain a PSCredential object, use the Get-Credential cmdlet.
For more information, type Get-Help Get-Credential.
Type: PSCredential
Parameter Sets: ComputerNameSet, ComputerNameAndPathSet, ComputerNameAndReferenceConfigurationSet
Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Detailed
Indicates that this cmdlet returns a detailed result of comparing the configuration document with the desired state of the nodes. The result includes information such as overall state, resources that are in the desired state, resources that are not in desired state, and computer name.
Type: SwitchParameter
Parameter Sets: ComputerNameSet, CimSessionSet
Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Path
Specifies the path of a folder that contains configuration document files. The cmdlet tests the configuration against the desired state of computers specified by the ComputerName or CimSession parameter.
Type: String
Parameter Sets: ComputerNameAndPathSet, CimSessionAndPathSet
Aliases:
Required: True
Position: 0
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-ReferenceConfiguration
Specifies the path of the configuration document file. This cmdlet tests the configuration against the actual state of computers specified by the ComputerName or CimSession parameter.
Type: String
Parameter Sets: ComputerNameAndReferenceConfigurationSet, CimSessionAndReferenceConfigurationSet
Aliases:
Required: True
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet.
If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer.
The throttle limit applies only to the current cmdlet, not to the session or to the computer.
Type: Int32
Parameter Sets: (All)
Aliases:
Required: False
Position: Named
Default value: None
