Re: rpcrt4: Use pseudo-random numbers to generate UUIDs rather than using the (old, deprecated) MAC-address-and-time generation algorithm (try 2)

The RFC recommends the following:

o  Set the two most significant bits (bits 6 and 7) of the
      clock_seq_hi_and_reserved to zero and one, respectively.

However, I don't see that done in your patch. Also, I don't know what
compatibility effect changing the algorithm will have on applications.
Have you checked which algorithm recent versions of Windows use and
what bits are set?
