OK, As I plan and plot this migration . This is what I think I wanna try to do. What do you thing of this - Our old NT server, has a Domain called Engineering. We were not retiring users, because in NT, if you retire a user you can never use it again. So when we retired jones for Susie Jones, when Tom Jones was hired we could not use jones as a user again. So we had to make user like tjones or jonest or jones1. When someone would leave we would just disable the account. We really never got into the roaming profiles or groups for that matter. I see that there are migration tools, but if we have 50 users that must authenticate, that is a high estimate. What I want to do is get the Linux/Samba box running, and maybe make a new domain, lets say Corporate. Because the users are all screwed up and I don't want to import all of them, I guess I could create them on this new machine. From what I read, I would have to add the user to unix, add the user to Samba, and if the machine is Win2k or XP, add the machine to the domain. Then I would move everyone over to this new domain. The old NT PDC has DHCP on it, excluding likethe first 75 ip's for the servers. I would have to set up DHCP the same way on the new server and disable it on the old one. Does this sound logical ??? We have a real, fussy application running on the old server, that I really can not change, nor change the client on the workstations - all of the stuff is written into the registry - we don't have support so I want to leave it on the old server until we can convert. We just may be able to pull this off. I never liked Microsoft's support. We may be better off on Linux or Unix.
