Our company has multiple D90D7 Dell WYSE Thin Clients that we have added to our domain. We have an absolute basic setup as far as their uses. They are used for one program, and to print. The issue is when we add these to the domain, and then lock it. At any random moment they will lose their trust relationship with the domain. I've tried a number of things from Blocking all inheritance from their account, and applying just what they need. Disabling any password change stuff, etc. Like I said all these people do is use one program, and to print from it. I can't figure out what to do to make this stop, and its hard to replicate to drill down the issue. It just merely happens. If anyone has any insight on this that would be great!! Thank you!
