The site I help support is soon to switch to 2003 Server w/AD. We have a mix of XP and Windows 2000 clients in our building and our Windows servers are still NT 4. Microsoft states Windows XP is the client fully support by Windows 2003 Server. I'm trying to anticipate limitations we'll face with our Windows 2000 clients when we transition from NT4 Servers to 2003 AD. I've been going through my reference books & MS white sheets, but can't find a lot of info on this. I know IE7 only works with XP. Does anyone know of limitations or problems I'm going to face with Win2k & 2003 Server? Thanks.
