That's the thing, there seems to be no correlation as to why the clients start ID'ing this way. I have a few windows 10, 1-2 windows 7. Some wireless, mostly wired. They all have been on Active Directory the whole time and have previously appeared on the client list with their Computer Name, or at least MAC, as the "Description". But one day they switched to using GUID. It's a very small number of clients that have switched to GUID to this point, but I'm watching more closely and will keep you posted if I start seeing more. and thanks for the reply!!
