Again, migration is ok, even feasible, for small environments. For large environments it gets complicated and is expensive and resource interaction can be an incredible pain to manage. Most likely since he has one DC he could pull off a migration ok, though upgrading the NT4 DC would still be easier and less chance to dork something up.
Logon caching doesn't solve all possible downtime issues, actually it solves one, you can log onto the desktop. Consider Exchange, authenticated proxies, file and print resources, etc. joe -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chandra Burra Sent: Thursday, January 13, 2005 3:10 PM To: [email protected] Subject: Re: [ActiveDir] Crazy question Its not clear weather he has the old NT box still on the network. A) If he has the existing NT box on the network its easy to migrate the users have him use ADMT and other shares on the the new box. B) if he does not.....start from the scratch...create all the users with same user names as they had before.... either way there would not be any down time as the users should be able to login to the cached profiles.
