Natural 2.2.3 Bufferpool Service and Windows Vista

is it possible to get the natural 2.2.3 buffer pool service working under windows vista ?
if i start the server with “NATBPSVC.EXE start” there occures no error-messages. but when i check the server with “NATBPSVC.EXE status” the server staus is “Service not active”
if i start an app like “NDERUN.EXE” a message box comes up “Natural Startup Error: 16 Unable to open buffer pool”. the same configuration works on windows xp without any error…
