## Restricting Access by Parallels Client Type and Build Number You can specify a minimum requirement for the Parallels Client type and version number in order for it to access the system. If a Parallels Client type is excluded or if its version is lower than the specified minimum, the device on which the Parallels Client is installed will be denied access. To specify the Parallels Client version requirement: In the RAS Console, select the Connection category and click the Allowed Devices tab. In the Mode drop-down list, select from the following options: Allow all clients to connect to the system. No restrictions. All Parallels Client types and versions are allowed access. Allow only the selected clients to connect to the system. Select this option and then select the desired Parallels Client types in the Clients list. To set the Minimum build value, right-click the client type and then click Properties in the context menu. Allow only the selected clients to list the published items. Select this option and then select the desired Parallels Client types in the Clients list. To set the Minimum build value, right-click the client type and then click Properties in the context menu. If a Parallels Client trying to connect to the system doesn't satisfy the requirements, the device user will receive an error and will be advised to contact the system administrator.
