Wow... This is great information: Microsoft recently published a couple series of helpful information for small- and medium-sized IT shops. It's a useful way for IT pro's in businesses with less than 50 employees (small-sized) or around 50-250 employees (medium-sized) to get a strong start of planning and designing IT projects that are secure and reliable, and that meet business needs. Small-solution details can be found at the link above.

For those responsible for all or part of a medium-sized business IT environment, Microsoft offers a whole slew of valuable information. The entire solution package can be downloaded here (with the exception of the beta papers, referenced below - you'll need to download those separately).

Introduction to the Medium IT Solution Series
Medium Business Solution for Core Infrastructure
Medium Business Solution for Management and Security using Active Directory Group Policy (beta)
Medium Business Solution for Messaging Services
Medium Business Solution for Collaboration Services
Medium Business Solution for Print Services
Medium Business Solution for Remote Connectivity
Medium Business Solution for Patch Management
Medium Business Solution for Client Configuration
Medium Business Guide for Antivirus
Medium Business Guide for Backup and Recovery
Medium Business Guide for Pilot Deployment and Migration (beta)

IT infrastructure is more and more complicated as time goes on - for Microsoft "shops," this information series can save time and help make sure your work is solid. There's information in these articles that I sound useful, and I've been pretty heavily involved in what's covered for several years now.
