Windows admin resources for seasoned Linux admins

Psiren writes: In six months or so my colleague is planning to leave and I will take over responsibility for the Windows servers. I have been a Linux/Unix sysadmin for many years, and have of course managed Windows machines in that time, but never to any great depth. I have worked closely with my colleague over the last few years to integrate our Windows and Linux systems as much as possible, so I am familiar with the basics, but am also well aware of the significant differences between the two. I am interested in finding resources that will be useful to help me in this transition. Recommendations for decent admin books for Windows Server 2003 would be a good start, especially those written from the more technical standpoint. Useful websites are generally a google away, but if you have any favourites I'd appreciate some links. Any other advice (other than "Don't do it!") is welcome.
