Stop-CsWindowsService enables you to stop a Microsoft Lync Server 2010 service.

Stop-CsWindowsService [-Name <String>] [-ComputerName <String>] [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-Graceful <SwitchParameter>] [-NoWait <SwitchParameter>] [-Report <String>] [-WhatIf [<SwitchParameter>]]
Stop-CsWindowsService [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-Graceful <SwitchParameter>] [-InputObject <NTService>] [-NoWait <SwitchParameter>] [-Report <String>] [-WhatIf [<SwitchParameter>]]

Many Lync Server 2010 components run as standard Windows services; for example, the Conferencing Attendant application is actually a service named RTCCAA. If you need to stop a Lync Server service, you can do so by using the Stop-CsWindowsService cmdlet.

Keep in mind that Stop-CsWindowsService can only stop Lync Server services; an error will occur if you attempt to stop a non-Lync Server service (such as the print spooler) using this cmdlet.

Functionally, Stop-CsWindowsService is very similar to the generic Windows PowerShell cmdlet Stop-Service; if you want, you could use Stop-Service to stop a Lync Server service. However, Stop-CsWindowsService includes a ComputerName parameter that makes it easy to stop a service on a remote computer: you simply include the ComputerName parameter followed by the fully qualified domain name (FQDN) of the remote computer. The Stop-Service cmdlet does not have a comparable parameter. In addition, Stop-CsWindowsService has a Report parameter that enables you to keep a log of any errors that might occur when calling Stop-CsWindowsService.

Stop-CsWindowsService does exactly what the name implies: it stops any service you ask it to stop. This includes services that have dependent services (services that can only run if the service you are attempting to stop is running). By default, if you try to stop a service that has dependent services, Stop-CsWindowsService will not only stop the service in question, but will stop all those dependent services as well. Because that could result in unexpected consequences, you can include the Graceful parameter when calling Stop-CsWindowsService. When you include the Graceful parameter, Stop-CsWindowsService will prevent the service from accepting any new requests. All existing service requests will remain as is; however, new requests will be rejected. As existing requests finish, those requests will not be replaced. Eventually, all the existing requests will be filled and the service will then shut down.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Stop-CsWindowsService cmdlet locally: RTCUniversalServerAdmins. In addition, you must also have local administrator rights on the destination computer in order to run this cmdlet. To return a list of all the role-based access control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC roles you have created yourself), run the following command from the Windows PowerShell prompt:

Get-CsAdminRole | Where-Object {$_.Cmdlets –match "Stop-CsWindowsService"}


Parameter Required Type Description




Name of the Lync Server service you want to stop. Note that you must use the service name (for example, RTCCAA) and not the service display name. You can only pass a single service name to the Name parameter, and you cannot use wildcards in the service name. You can use the Get-CsWindowsService cmdlet to retrieve service names.

Keep in mind that Stop-CsWindowsService can only stop Lync Server services; you cannot use this cmdlet to stop other Windows services. For those services, you might be able to use the Windows PowerShell  Stop-Service cmdlet.




Name of the remote computer running the service to be stopped; if this parameter is not included, then Stop-CsWindowsService will stop the specified service on the local computer. The remote computer should be referenced using its FQDN; for example,



Switch Parameter

Instead of immediately shutting down a service, waits until all existing service requests have been filled. (However, all new service requests will be rejected.) The service will not completely shut down until all the existing requests have been filled.



NTService object

Enables you to stop a service using an object reference rather than a service name. For example, if you use Get-CsWindowsService to return information about a service, and if you store the returned object in a variable named $x, you can then stop the service using this command:

$x = Get-CsWindowsService –Name "RTCCPS"

Stop-CsWindowsService -InputObject $x.Name



Switch Parameter

When present, causes the command to run and then immediately return control to the Windows PowerShell prompt. If not present, control will not be returned until the command has completed and a status report has been written to the screen.



Switch Parameter

Suppresses the display of any non-fatal error message that might occur when running the command.




Path to an HTML file where error information can be written. If this parameter is included, any errors that occur during the running of this cmdlet will be logged to the specified file (for example, C:\Logs\Service_report.html).



Switch Parameter

Describes what would happen if you executed the command without actually executing the command.



Switch Parameter

Prompts you for confirmation before executing the command.

Microsoft.Rtc.Management.Deployment.Core.NTService object. Stop-CsWindowsService accepts pipelined instances of the Windows service object.

None. Instead, Stop-CsWindowsService stops instances of the Microsoft.Rtc.Management.Deployment.Core.NTService object.

-------------------------- Example 1 ------------------------

Stop-CsWindowsService -Name "RTCRGS"

The command shown in Example 1 stops the Response Group application service on the local computer. The Response Group application service is identified by including the Name parameter and the name of that service: RTCRGS.

-------------------------- Example 2 ------------------------

Stop-CsWindowsService -Name "RTCRGS" -ComputerName

Example 2 also stops the Response Group application service; in this example, however, that service is located on the remote computer To stop a service on a remote computer, include the ComputerName parameter followed by the FQDN of the remote computer.

-------------------------- Example 3 ------------------------

Get-CsWindowsService | Where-Object {$_.DisplayName -like "*Call Park*"} | Stop-CsWindowsService

Example 3 demonstrates how you can stop a service even if you do not know the service name (in this example, RTCCPS). To do this, the command first calls Get-CsWindowsService without any parameters in order to return a collection of all the Lync Server services on the local computer. This complete collection is then piped to the Where-Object cmdlet, which selects only those services where the DisplayName property includes the string value "Call Park". The filtered collection is then piped to Stop-CsWindowsService, which stops the Call Park application service.
