HPDM doesnt see any of my thin clients anymore

A few months ago I setup an HPDM server on Win 2012r2 along with 12 HP thin clients, Mainly mt245. I could see all of the thin clients with HPDM, I even used it to Image all of them.

Yesterday, I went to add a new mt245 abd image it. All of the TCs are gone from HPDM and it doesnt find this new one. I've tried walking the range. I've tried adding it manually as well as telling it to walk the range of the exact IP that the TC has. I can ping the TC from the server and vice-versa.

Windows firewall is completly off.

Any thoughts?

Thanks,

Travis
