I think you better explain a little better. You are suggesting to not having any XP machine on a Windows 2000 Domain. It is highly irresponsible to make an accusation like that on a forum without offering proof. Most likely, as others have said, there is a misconfiguration on your network.

First of all it is my recommendation not to add a windows xp client to a windows2000 domain controller. I am speaking from experience with this. XP slows down both the client and the server and the authentication method seems somewhat reversible. Keep at windows2000 until a patch is released to fix this problem. With Kind Regards, Khan. ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jtolmachoff@xxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
