Windows 2008 R2 changes to Public Firewall Profile

If like us sometimes something just goes wrong and you get that call that "all our applications have stopped working" but your Managed Services application says all is good.  It could be this.

The Network Awareness Location Service.  This server is what determines which Windows Firewall Policy you get on a workstation or server and sometimes it goes wrong and sets a server on a Public Firewall profile.  When this happens applications just stop as all incoming ports are pretty much shut down.  So when everything looks great but no one can work check this one out.

Have a read of this Blog from Microsoft on the NLA Service.

It could just save your bacon.
