Adding legacy computers to a domain

We have approx 20 Mazak milling machines running either Win 95, Win 2000 Pro or Win XP. Since the beginning of the year I've not been able to re-add them back onto the domain (functional level 2016). As they are old a hard drive replacement is often needed to keep them going but its like for like, the Mazak engineer will replace a machine running Win 2000 Pro with a new hard drive with the same OS. They then leave us, the IT dept to re-add them back onto the domain. This is where the issue is.

The machines live on a segregated VLAN separate from our normal network. Theyll have their static IPs set then attempted to add back onto the domain. This fails with a "an internal error " or more often "the specified name is no longer available". The attempted re-join can create an AD entry but its immediately disabled and accessing the computer from another computer shows a "Trust relationship" error.

Now there's loads of stuff on the internet about this and Win XP does have a workaround (install SP3 and KB969442) but nothing available for 2000 or 95.

Can anyone help or suggest the best way for these multi million pound machines to be accessed?

Can any shed any light on why this happened in the first place (server update possibly)?

"Scrap the lot" I hear people say but to replace them is a lot of money, well into 7 or 8 figures so our task is to keep them going for a while longer. 😒

Thank you

Steve
