This post does not specifically apply to the SBS server per-se but rather to a common configuration that is used in SBS networks where a second server is added either by purchasing the
SBS 2011 Premium Add-on
,
Windows MultiPoint Server
(WMS) or a stand-alone server and used as a Remote Desktop Server.
If you are running
Windows MultiPoint Server 2011
or Windows Server 2008 R2 server you may run into this behavior and we recommend taking preventive action, especially to prevent this issue in WMS.
Symptoms
RDS clients are getting dropped/reconnected to WMS server. You will usually see the client go into reconnecting 1 of 20 times, and then reconnect shortly afterwards.
If you open the event logs, and go to the Microsoft-Windows-NetworkProfile/Operational events, you will see this at the times of the drop:

Resolution
Apply the hotfix mentioned in
http://support.microsoft.com/kb/2524478
to the WMS or Remote Desktop Server running 2008 R2.
Long term plans are being finalized to provide an automated solution for WMS customers, we will update this post when they are completed.
