DF bit change in Windows Server 2008 R2

can change df bit in windows server 2008 r2? 

what understand cannot change df in windows server 2008 r2, df bit set default on tcp traffic, icmp can use "-f"

wht difference between mtu , df bit



mtu maximum transmission unit (the size of box in packets travel). df (don't fragment) instructs router drop packets instead of breaking them smaller pieces when given packet bigger mtu allows.

in windows vista/2008 , later, mtu managed automatically, believe can set enablepmtubhdetect to 1 set df bit.
