The underlying operating system in Windows Home Server 2011, Windows Small Business Server 2011 Essentials, and Windows Storage Server 2008 R2 Essentials allows a maximum of two simultaneous Remote Desktop connections to the server. A direct result of this is that only two allowed users can be connected to WHS RemoteApp, WHS Office, WHS Outlook, WHS QuickBooks and/or WHS Quicken at exactly the same time.
If two active remote connections already exist on the server when an allowed user signs in to the add-in, they will receive a (sometimes hard-to-read) message from the server asking them to select a user to disconnect so that they may login:
To work-around this two concurrent users limitation of your server, you can enable the add-in’s “multiple simultaneous connections” feature as follows:
IMPORTANT: Enabling multiple simultaneous connections is optional, and NOT OFFICIALLY SUPPORTED. The customer fully assumes all risk, responsibility, and liability associated with enabling multiple simultaneous connections to their server. It is recommended that a server backup be performed before enabling multiple simultaneous connections. See the “Server backup and restore” section of the following web page for more information on configuring server backup, running server backup, and recovering the server: Manage Backup and Restore
1. Select “Dashboard” from the Launchpad application and sign in to open the server Dashboard application.
2. Click on the add-in’s icon in the navigation pane, and then click on “Enable Simultaneous Connections“.
NOTE: The “Enable Simultaneous Connections” feature is only available after the add-in has been registered. The feature is not available in the 2 user Student Edition.
3. If you fully understand and agree to the specified terms, click Yes in order to enable multiple simultaneous connections to your server:
4. A server restart is required to finish enabling multiple simultaneous connections:
Clicking Yes will restart the server after 30 seconds:
Clicking No will remind you that multiple simultaneous connections will not be enabled until the server has been restarted:
5. After the server restarts, you can verify that multiple simultaneous connections have been enabled by clicking on the “Enable Simultaneous Connections” task again:
Multiple users can now be connected to WHS RemoteApp, WHS Office, WHS Outlook, WHS QuickBooks, and/or WHS Quicken at the exact same time (up to the user limit of your license and/or the performance limits of your server/network).
