Disabling IP v6 can crash a SBS 2008 server. Who new?

A few months ago I setup a SBS 2008 server for a client. As I was going through my setup checklist I unchecked IP v6 on the adapter. My thought was disable anything that's not being used on the server. Last night we had some strong storms run though and they got their power knocked out long enough for the the UPS's to shut the servers down. When the server came back up exchange crashed.

Long story short apparently SBS 2008 will crash if you disable IP v6 on the adapter...

Here is a link to the official MS SBS blog site that details the problem and how to properly disable IP v6.
