Is there any chance that a GUID will be duplicated if I create it from
different threads in an applications in a multiCPU machine using
Guid.NewGuid();
Thanks

Not likely, although possible in theory.

nope if the machine has a network card (the guid algorithm uses the mach
address)

Ok, I know the alogorithm will be using the mac address of networkcard, time
and X(I dont knnow) parameters
There is a chance that, the time will be same, can somebody tell about other
parameters,
Does it include the threadid or process id or something like that to make it
unique.
Thanks
Bipin
