Hi everyone !

Today I will spotlight a really good article for any network administrator. It's the article Root Causes for Slow Boots and Logons (sbsl) !

(Editor's note: SBSL is the acronym for Slow Boot, Slow logon.)

It's an article with a lot of tips. It's an all-around article that lists any products and patches that can cause slowness with any Windows end-user OS. 

What I like from the article is that it gets into the details about how to find the culprit of the slownes;
- Applications, Hardware, Locator, Network, Operating System, Policy including Group Policy Preferences, Profiles, Readyboot , Remote Desktop, WMI  

There are simple tips in that document that I used in the past to get a drop from 2 minutes to a 30-second login by tweaking some GPO... so if you extend that to an entire IT park, you gain a lot of productivity!! :)

Here is a sample quote from the article:

This article describes Microsoft Support experiences in troubleshooting boot and logon delays, specifically the root causes. Other related topics include:

http://social.technet.microsoft.com/wiki/contents/articles/11341.the-windows-7-boot-process-sbsl.aspx

The goal of this content is to create awareness among IT administrators, support professionals, and consultants, about the tools, causes, and resolutions for boot and user logon delays.The primary focus is on domain-joined clients and servers.The article does not pertain to slow boots and logons on consumer desktops in a workgroup, but some of the tools and methods would still apply, such as enabling verbose logging and noting the message and duration where the boot or logon hung.

There is no shortage of root causes for boot and logon delays. Some delays are caused by code-defects in the OS or applications on the computer experiencing slow boot or logon. Other root causes lie with the underlying network, remote servers, or Administrator misconfiguration.
Don’t worry about tracking the QFEs for Windows. We’ll be publishing a list of recommended fixes the near future.
The following sections explain some of the problems that have been seen to date, and how to resolve them.

Thanks for your time !

P.S. That article is a really good example of a good collaboration with a Microsoft product team on TechNet Wiki!!
