I've been a \*nix (from VMS to Linux to FreeBSD to Solaris etc) admin for the past five years and I have just recently had it dumped on my plate that i am going to be running some Windows Servers.

I'm looking for some resources -- some learning materials to get me up to speed on basic operation and administration of Windows Server 2003/2008. I don't expect to learn the intricacies immediately -- that will come with experience -- but I do want to know the basics to provide a foundation of knowledge.

I'm looking to learn the basics of the most common roles and features -- I've already built myself a domain controller and domain in a VM and have set up a member on another box that also hosts file services.

I have been reading sites like StackOverflow to see issues people experience with actual, in service stuff and have learned a bit from that.

Additionally, does MS have any e-learning materials? What about e-certifications?

Any direction at all is very much appreciated.
