# InternetTimeout Property Example (VC++)
> [!IMPORTANT]
>  Beginning with Windows 8 and Windows Server 2012, RDS server components are no longer included in the Windows operating system (see Windows 8 and [Windows Server 2012 Compatibility Cookbook](https://www.microsoft.com/download/details.aspx?id=27416) for more detail). RDS client components will be removed in a future version of Windows. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Applications that use RDS should migrate to [WCF Data Service](https://go.microsoft.com/fwlink/?LinkId=199565).  
  
 This example demonstrates the [InternetTimeout](../../../ado/reference/rds-api/internettimeout-property-rds.md) property, which exists on the [DataControl](../../../ado/reference/rds-api/datacontrol-object-rds.md) and [DataSpace](../../../ado/reference/rds-api/dataspace-object-rds.md) objects. In this case, the **InternetTimeout** property is demonstrated on the **DataControl** object and the timeout is set to 20 seconds.
