How does ESET client identify itself to ERAS?

We're about to place our ESS client on a disk image and I was wondering if each client has a unique identifier to differentiate itself in ERAS.

I was told by an ESET tech that the clients use the MAC address as the identifier but I wasn't exactly reassured by his answer. He didn't sound confident of that.

Have any of you installed ESET on a disk imaged and deployed it successfully? That is, the newly imaged computers report into ERAS without appearing as duplicates.

Thanks,

From what I have found they use the Computer name (without the FQDN) plus the MAC address, and that's it.

I ran into this because I had two machines at two sites (two different networks) with the same name. They'd be fine unless I allowed the Computer renaming option, at which point the two computers would keep over-writing each-other in the RAS.
