I have two WHS 2011 boxes at two different locations and they are both exhibiting the same problem. The client computers are randomly disconnecting from the server and are
unable to reconnect unless I uninstall the Windows Home Server Connector software and reinstall it. I have seen this more than once on one server and the other, which I just installed a couple of days ago, just kicked two of its three clients off last night.
The client that remains connected installed about 6 updates last night but I can't confirm anything about the two that are currently offline.
Anyone else seeing this problem. It seems like it should be a known issue.
