Greetings This is not really exchange related, but I have had a real good response from you guys that I thought I would ask you opinion about this one. I am running windows 2000, obviously with AD, from time to time my users get locked out, after I reset there passwords, they get prompted to change there passwords, the message that the domain is not available comes up. I resolve this by re-adding the machine to my domain, this is not an acceptable resolution, as it is rather time consuming. I also find that the users accounts get locked out for no apparent reason. I would really appreciate some feed back, as I have found nothing on the web or TechNet.
