Windows MultiPoint Server Disconnects

There is a known issue with Windows Server 2008 R2 (and Windows 7) that causes the network interface to change “location” from a Domain network to a Public network under some conditions. This is described in MS KnowledgeBase article: 2524478. The situation that causes this is made more likely to happen on a WMS server because of the Loop Back Adapters. I’ve been running this particular hotfix here for more than a week, with no ill effects. And a whole lot fewer WMS disconnects from my RDP clients! If you are using WMS, and using RDP clients, I strongly recommend that you download a copy of this hot fix and apply it if you’re seeing any unexplained disconnects from these clients.

Update1: There’s a new blog post up on the Official SBS Blog that talks about this. If you’re running WMS, you really want to get this hotfix.

Update2: If you’re running through a Remote Desktop Gateway (RD Gateway) to connect to your WMS server, you should install this hotfix on the RDGateway box as well. For example, on my SBS 2011 Standard network, my laptops use applications on the WMS server using RemoteApps. But I have them set to go through the RD Gateway on my SBS server, even when I’m in the office. This allows my connections to stay the same regardless of whether I’m in the office or on the road. I was still getting some disconnects even after installing this hotfix on the WMS server. But when I added them to the SBS server (my RD Gateway, remember), the disconnects went away. I haven’t had one all day. WOOT!
