How Does Domain/Forest Functional Level of 2K3 Effect Windows 2000 Clients?

Posted on 2006-05-16

I have a Windows 2K3 server running AD.

The domain is currently in Windows 2000 mixed and the Forest is in Windows 2000 functional level.

If I raise the forest and domain functional levels to 2K3, how will that affect my Windows 2000 client PC's?

Will they still be able to log on to the domain?

I'm pretty sure this only affects DC's but I'd like to know for sure before I change it as its irreversible.

    Hi yvsupport,

    no effect on your clients at all, you know, i take it, that any NT or 98 clients are gone with native mode

    2003 mode is just for domain controllers, you wont notice a thing

    No NT or 98, Just 2K and XP.
