Hi all,
  I am trying to fetch the MACID of my System using UUID
structure.the last 12 digits gives the MACID,but there is a problem
in
windows 2000 machine that  this MacID gives me  different values
every
time when  i execute  UuidCreateSequential for the same machine......
what might be the problem,help in this regard is highly Appreciated.

Better choice is GetAdapterInfo. There may be two reasons to see
different MAC address everytime.

1) Just a quick verification is to check that you dont have multiple
network adapter.

2) One more thing, I am not sure which MAC adress UuidCreateSequential
uses to generate UUID. Your machine can have two MAC adrress, one is
permanent (real) and one is current (virtual). An user/app is allowed
to change the current ethernet address. May be some app is
consistently changing the current address ( dont see any added value
behind this, but may be) and if UuidCreateSequential uses this Current
Mac address to generate UUID then everytime u will see a new MAC
address.

To add more UuidCreateSequential is just another method to get the MAC
address. But MS suggests,an user shd go for GerAdaptersInfo.
