This is a question that often crops up in a few circles. The idea behind network teaming is the ability to take multiple physical cards and to “bind” them together to make them appear as a single network card to the operating system. Typically you would do this for redundancy and “performance” reasons on your network. HP and Dell and others do this via the additional of specific drivers. These drivers attempt to make the multiple physical network cards look like a single network card to the operating system.
In an SBS network environment, Microsoft have designed the various wizards, Best Practice Analysers and the like to use only a single physical network card. This means that if you try to configure Network Teaming on an SBS 2008 or SBS 2011 server, you will get some very uncertain results. I’ve heard of people having issues with things like the server sitting at “Preparing Network Connections” for hours on end.
The end solution in all cases is that SBS 2008 and SBS 2011 do NOT support network teaming. They only support a single physical network card. Trying to make things work beyond this is totally unsupported by Microsoft.
