Default gateway disappears after restarting SBS 2008 server

Everytime you restart a Small Business Server 2008 the default gateway disappears.

Solution: When you take a look at the following registry key: HKLM/System/CurrentControlSet/Services/Tcpip/Parameters/Interfaces/ CLSID of the network card this is happening for, you’ll probably notice it by viewing the ipaddress value. Then open the “DefaultGateway” value. In our case you see the default gateway but above it there is an empty line. After removing the empty line, restarting works fine and the problem didn’t occur anymore.

Additonal information can be found on the official SBS blog

      Did you setup your SBS 2011 server using the Wizards? if so run the Fix my network wizard this is there to change the network related settings. YOu should Always run this wizard after you changed ip settings.
