Re: [DUG]: Unique Machine ID....

[Nello Sestini]

OLE GUIDs?   (generated on the machine they are intended to identify)   for machines with NICs part of the GUID will be the MAC address of the NIC   not sure what those bits are for non-NIC machines but the MS folklore is that the identifiers are unique regardless  (with very high probablity).   Of course if this is for a copy protection scheme or something it's not crack proof because someone can just copy over the id from another machine.    But for generating unique DB keys by workstation or something like that it is ok I think   -ns ----- Original Message ----- From: Donovan J.

I need to come up with a unique identifier for a machine. For my purposes a NIC address would be sufficient. I am willing to wear the small chance that two network cards would have the same NIC address. However the concern I do have is for a computer that does not have a NIC but only a dial up connection. Obviously then there is no NIC address? Can someone comment on that? Also, if anyone has a relatively simple mechanism to obtain a unique ID for each machine I would be much obliged. -- Donovan ---------------------------------------------------------------------- Donovan J.
