Enable 2008Server in DropBox (See 12289) (rebased onto develop)



This is the same as gh-2524 but rebased onto develop.

----

Tested on ome-win2008-x86 in place with the 5.0.2-rc1 server. DropBox should successfully start under Windows 2008 Server edition. Check `var\log\MonitorServer.log` and `var\log\DropBox.log` for any errors.
