Duplicate GUID on Dell Optiplex GX620
I have never seen this before. We received a replacement motherboard (all in one) for one of our small form factor Optiplex GX620. I deleted the old computer account and began to set up another only to be halted with a duplicate GUID error message. Sure enough there was another machine on the network with exactly the same GUID.
I noted down the number and off I went the relevant computer. Sure enough it is identical. Anyone else had this and is there a way of programming a new GUID on the the NIC?
